| CVE-2022-49613 | 1 Linux | 1 Linux Kernel | 2025-10-23 | N/A | 5.5 MEDIUM |
| In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fix PM usage_count for console handover When console is enabled, univ8250_console_setup() calls serial8250_console_setup() before .dev is set to uart_port. Therefore, it will not call pm_runtime_get_sync(). Later, when the actual driver is going to take over univ8250_console_exit() is called. As .dev is already set, serial8250_console_exit() makes pm_runtime_put_sync() call with usage count being zero triggering PM usage count warning (extra debug for univ8250_console_setup(), univ8250_console_exit(), and serial8250_register_ports()): [ 0.068987] univ8250_console_setup ttyS0 nodev [ 0.499670] printk: console [ttyS0] enabled [ 0.717955] printk: console [ttyS0] printing thread started [ 1.960163] serial8250_register_ports assigned dev for ttyS0 [ 1.976830] printk: console [ttyS0] disabled [ 1.976888] printk: console [ttyS0] printing thread stopped [ 1.977073] univ8250_console_exit ttyS0 usage:0 [ 1.977075] serial8250 serial8250: Runtime PM usage count underflow!

This problem became apparent only recently because 82586a721595 ("PM: runtime: Avoid device usage count underflows") added the warning printout. I confirmed this problem also occurs with v5.18 (w/o the warning printout, obviously). | |||||
| CVE-2022-49612 | 1 Linux | 1 Linux Kernel | 2025-10-23 | N/A | 7.8 HIGH |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: core: Fix boundary conditions in interpolation The functions power_supply_temp2resist_simple and power_supply_ocv2cap_simple handle boundary conditions incorrectly. The change was introduced in a4585ba2050f460f749bbaf2b67bd56c41e30283 ("power: supply: core: Use library interpolation"). There are two issues: First, the lines "high = i - 1" and "high = i" in ocv2cap have the wrong order compared to temp2resist. As a consequence, ocv2cap sets high=-1 if ocv>table[0].ocv, which causes an out-of-bounds read. Second, the logic of temp2resist is also not correct. Consider the case table[] = {{20, 100}, {10, 80}, {0, 60}}. For temp=5, we expect a resistance of 70% by interpolation. However, temp2resist sets high=low=2 and returns 60. | |||||

| CVE-2022-49610 | 1 Linux | 1 Linux Kernel | 2025-10-23 | N/A | 5.5 MEDIUM |
| In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Prevent RSB underflow before vmenter On VMX, there are some balanced returns between the time the guest's SPEC_CTRL value is written, and the vmenter. Balanced returns (matched by a preceding call) are usually ok, but it's at least theoretically possible an NMI with a deep call stack could empty the RSB before one of the returns. For maximum paranoia, don't allow *any* returns (balanced or otherwise) between the SPEC_CTRL write and the vmenter. [ bp: Fix 32-bit build. ] | |||||
| CVE-2022-49606 | 1 Linux | 1 Linux Kernel | 2025-10-23 | N/A | 5.5 MEDIUM |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix sleep from invalid context BUG Taking the qos_mutex to process RoCEv2 QP's on netdev events causes a kernel splat. Fix this by removing the handling for RoCEv2 in irdma_cm_teardown_connections that uses the mutex. This handling is only needed for iWARP to avoid having connections established while the link is down or having connections remain functional after the IP address is removed.

| CVE-2022-49605 | 1 Linux | 1 Linux Kernel | 2025-10-23 | N/A | 5.5 MEDIUM |
| In the Linux kernel, the following vulnerability has been resolved: igc: Reinstate IGC_REMOVED logic and implement it properly The initially merged version of the igc driver code (via commit 146740f9abc4, "igc: Add support for PF") contained the following IGC_REMOVED checks in the igc_rd32/wr32() MMIO accessors: u32 igc_rd32(struct igc_hw *hw, u32 reg) { u8 __iomem *hw_addr = READ_ONCE(hw->hw_addr); u32 value = 0; if (IGC_REMOVED(hw_addr)) return ~value; value = readl(&hw_addr[reg]); /* reads should not return all F's */ if (!(~value) && (!reg || !(~readl(hw_addr)))) hw->hw_addr = NULL; return value; } And: #define wr32(reg, val) \ do { \ u8 __iomem *hw_addr = READ_ONCE((hw)->hw_addr); \ if (!IGC_REMOVED(hw_addr)) \ writel((val), &hw_addr[(reg)]); \ } while (0) E.g. igb has similar checks in its MMIO accessors, and has a similar macro E1000_REMOVED, which is implemented as follows: #define E1000_REMOVED(h) unlikely(!(h)) These checks serve to detect and take note of an 0xffffffff MMIO read return from the device, which can be caused by a PCIe link flap or some other kind of PCI bus error, and to avoid performing MMIO reads and writes from that point onwards. However, the IGC_REMOVED macro was not originally implemented: #ifndef IGC_REMOVED #define IGC_REMOVED(a) (0) #endif /* IGC_REMOVED */ This led to the IGC_REMOVED logic to be removed entirely in a subsequent commit (commit 3c215fb18e70, "igc: remove IGC_REMOVED function"), with the rationale that such checks matter only for virtualization and that igc does not support virtualization -- but a PCIe device can become detached even without virtualization being in use, and without proper checks, a PCIe bus error affecting an igc adapter will lead to various NULL pointer dereferences, as the first access after the error will set hw->hw_addr to NULL, and subsequent accesses will blindly dereference this now-NULL pointer. This patch reinstates the IGC_REMOVED checks in igc_rd32/wr32(), and implements IGC_REMOVED the way it is done for igb, by checking for the unlikely() case of hw_addr being NULL. This change prevents the oopses seen when a PCIe link flap occurs on an igc adapter. | |||||
| CVE-2024-58009 | 1 Linux | 1 Linux Kernel | 2025-10-22 | N/A | 5.5 MEDIUM |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc A NULL sock pointer is passed into l2cap_sock_alloc() when it is called from l2cap_sock_new_connection_cb() and the error handling paths should also be aware of it. Seemingly a more elegant solution would be to swap bt_sock_alloc() and l2cap_chan_create() calls since they are not interdependent to that moment but then l2cap_chan_create() adds the soon to be deallocated and still dummy-initialized channel to the global list accessible by many L2CAP paths. The channel would be removed from the list in short period of time but be a bit more straight-forward here and just check for NULL instead of changing the order of function calls.

| In the Linux kernel, the following vulnerability has been resolved: nvkm: correctly calculate the available space of the GSP cmdq buffer r535_gsp_cmdq_push() waits for the available page in the GSP cmdq buffer when handling a large RPC request. When it sees at least one available page in the cmdq, it quits the waiting with the amount of free buffer pages in the queue. Unfortunately, it always takes the [write pointer, buf_size) as available buffer pages before rolling back and wrongly calculates the size of the data should be copied. Thus, it can overwrite the RPC request that GSP is currently reading, which causes GSP hang due to corrupted RPC request: [ 549.209389] ------------[ cut here ]------------ [ 549.214010] WARNING: CPU: 8 PID: 6314 at drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:116 r535_gsp_msgq_wait+0xd0/0x190 [nvkm] [ 549.225678] Modules linked in: nvkm(E+) gsp_log(E) snd_seq_dummy(E) snd_hrtimer(E) snd_seq(E) snd_timer(E) snd_seq_device(E) snd(E) soundcore(E) rfkill(E) qrtr(E) vfat(E) fat(E) ipmi_ssif(E) amd_atl(E) intel_rapl_msr(E) intel_rapl_common(E) mlx5_ib(E) amd64_edac(E) edac_mce_amd(E) kvm_amd(E) ib_uverbs(E) kvm(E) ib_core(E) acpi_ipmi(E) ipmi_si(E) mxm_wmi(E) ipmi_devintf(E) rapl(E) i2c_piix4(E) wmi_bmof(E) joydev(E) ptdma(E) acpi_cpufreq(E) k10temp(E) pcspkr(E) ipmi_msghandler(E) xfs(E) libcrc32c(E) ast(E) i2c_algo_bit(E) crct10dif_pclmul(E) drm_shmem_helper(E) nvme_tcp(E) crc32_pclmul(E) ahci(E) drm_kms_helper(E) libahci(E) nvme_fabrics(E) crc32c_intel(E) nvme(E) cdc_ether(E) mlx5_core(E) nvme_core(E) usbnet(E) drm(E) libata(E) ccp(E) ghash_clmulni_intel(E) mii(E) t10_pi(E) mlxfw(E) sp5100_tco(E) psample(E) pci_hyperv_intf(E) wmi(E) dm_multipath(E) sunrpc(E) dm_mirror(E) dm_region_hash(E) dm_log(E) dm_mod(E) be2iscsi(E) bnx2i(E) cnic(E) uio(E) cxgb4i(E) cxgb4(E) tls(E) libcxgbi(E) libcxgb(E) qla4xxx(E) [ 549.225752] iscsi_boot_sysfs(E) iscsi_tcp(E) libiscsi_tcp(E) libiscsi(E) scsi_transport_iscsi(E) fuse(E) [last unloaded: gsp_log(E)] [ 549.326293] CPU: 8 PID: 6314 Comm: insmod Tainted: G E 6.9.0-rc6+ #1 [ 549.334039] Hardware name: ASRockRack 1U1G-MILAN/N/ROMED8-NL, BIOS L3.12E 09/06/2022 [ 549.341781] RIP: 0010:r535_gsp_msgq_wait+0xd0/0x190 [nvkm] [ 549.347343] Code: 08 00 00 89 da c1 e2 0c 48 8d ac 11 00 10 00 00 48 8b 0c 24 48 85 c9 74 1f c1 e0 0c 4c 8d 6d 30 83 e8 30 89 01 e9 68 ff ff ff <0f> 0b 49 c7 c5 92 ff ff ff e9 5a ff ff ff ba ff ff ff ff be c0 0c [ 549.366090] RSP: 0018:ffffacbccaaeb7d0 EFLAGS: 00010246 [ 549.371315] RAX: 0000000000000000 RBX: 0000000000000012 RCX: 0000000000923e28 [ 549.378451] RDX: 0000000000000000 RSI: 0000000055555554 RDI: ffffacbccaaeb730 [ 549.385590] RBP: 0000000000000001 R08: ffff8bd14d235f70 R09: ffff8bd14d235f70 [ 549.392721] R10: 0000000000000002 R11: ffff8bd14d233864 R12: 0000000000000020 [ 549.399854] R13: ffffacbccaaeb818 R14: 0000000000000020 R15: ffff8bb298c67000 [ 549.406988] FS: 00007f5179244740(0000) GS:ffff8bd14d200000(0000) knlGS:0000000000000000 [ 549.415076] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 549.420829] CR2: 00007fa844000010 CR3: 00000001567dc005 CR4: 0000000000770ef0 [ 549.427963] PKRU: 55555554 [ 549.430672] Call Trace: [ 549.433126] <TASK> [ 549.435233] ? __warn+0x7f/0x130 [ 549.438473] ? r535_gsp_msgq_wait+0xd0/0x190 [nvkm] [ 549.443426] ? report_bug+0x18a/0x1a0 [ 549.447098] ? handle_bug+0x3c/0x70 [ 549.450589] ? exc_invalid_op+0x14/0x70 [ 549.454430] ? asm_exc_invalid_op+0x16/0x20 [ 549.458619] ? r535_gsp_msgq_wait+0xd0/0x190 [nvkm] [ 549.463565] r535_gsp_msg_recv+0x46/0x230 [nvkm] [ 549.468257] r535_gsp_rpc_push+0x106/0x160 [nvkm] [ 549.473033] r535_gsp_rpc_rm_ctrl_push+0x40/0x130 [nvkm] [ 549.478422] nvidia_grid_init_vgpu_types+0xbc/0xe0 [nvkm] [ 549.483899] nvidia_grid_init+0xb1/0xd0 [nvkm] [ 549.488420] ? srso_alias_return_thunk+0x5/0xfbef5 [ 549.493213] nvkm_device_pci_probe+0x305/0x420 [nvkm] [ 549.498338] local_pci_probe+0x46/ ---truncated--- | |||||

| In the Linux kernel, the following vulnerability has been resolved: be2net: Fix buffer overflow in be_get_module_eeprom be_cmd_read_port_transceiver_data assumes that it is given a buffer that is at least PAGE_DATA_LEN long, or twice that if the module supports SFF 8472. However, this is not always the case. Fix this by passing the desired offset and length to be_cmd_read_port_transceiver_data so that we only copy the bytes once. | |||||

The lbr_from_signext_quirk_needed() is introduced to determine whether the TSX quirk should be applied. However, the lbr_from_signext_quirk_needed() is invoked before the intel_pmu_lbr_init(), which parses the LBR format information. Without the correct LBR format information, the TSX quirk never be applied. Move the lbr_from_signext_quirk_needed() into the intel_pmu_lbr_init(). Checking x86_pmu.lbr_has_tsx in the lbr_from_signext_quirk_needed() is not required anymore. Both LBR_FORMAT_EIP_FLAGS2 and LBR_FORMAT_INFO have LBR_TSX flag, but only the LBR_FORMAT_EIP_FLAGS2 requirs the quirk. Update the comments accordingly. | |||||

| In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Use __try_cmpxchg_user() to update guest PTE A/D bits Use the recently introduced __try_cmpxchg_user() to update guest PTE A/D bits instead of mapping the PTE into kernel address space. The VM_PFNMAP path is broken as it assumes that vm_pgoff is the base pfn of the mapped VMA range, which is conceptually wrong as vm_pgoff is the offset relative to the file and has nothing to do with the pfn. The horrific hack worked for the original use case (backing guest memory with /dev/mem), but leads to accessing "random" pfns for pretty much any other VM_PFNMAP case. | |||||

| Unity Runtime before 2025-10-02 on Android, Windows, macOS, and Linux allows argument injection that can result in loading of library code from an unintended location. If an application was built with a version of Unity Editor that had the vulnerable Unity Runtime code, then an adversary may be able to execute code on, and exfiltrate confidential information from, the machine on which that application is running. NOTE: product status is provided for Unity Editor because that is the information available from the Supplier. However, updating Unity Editor typically does not address the effects of the vulnerability; instead, it is necessary to rebuild and redeploy all affected applications. | |||||

| In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: validate BOOT sectors_per_clusters When the NTFS BOOT sectors_per_clusters field is > 0x80, it represents a shift value. Make sure that the shift value is not too large before using it (NTFS max cluster size is 2MB). Return -EVINVAL if it too large. This prevents negative shift values and shift values that are larger than the field size. Prevents this UBSAN error: UBSAN: shift-out-of-bounds in ../fs/ntfs3/super.c:673:16 shift exponent -192 is negative | |||||

| In the Linux kernel, the following vulnerability has been resolved: zsmalloc: fix races between asynchronous zspage free and page migration The asynchronous zspage free worker tries to lock a zspage's entire page list without defending against page migration. Since pages which haven't yet been locked can concurrently migrate off the zspage page list while lock_zspage() churns away, lock_zspage() can suffer from a few different lethal races. It can lock a page which no longer belongs to the zspage and unsafely dereference page_private(), it can unsafely dereference a torn pointer to the next page (since there's a data race), and it can observe a spurious NULL pointer to the next page and thus not lock all of the zspage's pages (since a single page migration will reconstruct the entire page list, and create_page_chain() unconditionally zeroes out each list pointer in the process). Fix the races by using migrate_read_lock() in lock_zspage() to synchronize with page migration. | |||||

| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_qca: Use del_timer_sync() before freeing While looking at a crash report on a timer list being corrupted, which usually happens when a timer is freed while still active. This is commonly triggered by code calling del_timer() instead of del_timer_sync() just before freeing. One possible culprit is the hci_qca driver, which does exactly that. Eric mentioned that wake_retrans_timer could be rearmed via the work queue, so also move the destruction of the work queue before del_timer_sync(). | |||||
