| CVE-2023-54162 | 1 Linux | 1 Linux Kernel | 2025-12-31 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix possible memory leak in smb2_lock() argv needs to be free when setup_async_work fails or when the current process is woken up. | ||||
| CVE-2023-54183 | 1 Linux | 1 Linux Kernel | 2025-12-31 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: media: v4l2-core: Fix a potential resource leak in v4l2_fwnode_parse_link() If fwnode_graph_get_remote_endpoint() fails, 'fwnode' is known to be NULL, so fwnode_handle_put() is a no-op. Release the reference taken from a previous fwnode_graph_get_port_parent() call instead. Also handle fwnode_graph_get_port_parent() failures. In order to fix these issues, add an error handling path to the function and the needed gotos. | ||||

| In the Linux kernel, the following vulnerability has been resolved: tracing: Fix warning in trace_buffered_event_disable() Warning happened in trace_buffered_event_disable() at WARN_ON_ONCE(!trace_buffered_event_ref) Call Trace: ? __warn+0xa5/0x1b0 ? trace_buffered_event_disable+0x189/0x1b0 __ftrace_event_enable_disable+0x19e/0x3e0 free_probe_data+0x3b/0xa0 unregister_ftrace_function_probe_func+0x6b8/0x800 event_enable_func+0x2f0/0x3d0 ftrace_process_regex.isra.0+0x12d/0x1b0 ftrace_filter_write+0xe6/0x140 vfs_write+0x1c9/0x6f0 [...] The cause of the warning is in __ftrace_event_enable_disable(), trace_buffered_event_enable() was called once while trace_buffered_event_disable() was called twice. Reproduction script show as below, for analysis, see the comments: ``` #!/bin/bash cd /sys/kernel/tracing/ # 1. Register a 'disable_event' command, then: # 1) SOFT_DISABLED_BIT was set; # 2) trace_buffered_event_enable() was called first time; echo 'cmdline_proc_show:disable_event:initcall:initcall_finish' > \ set_ftrace_filter # 2. Enable the event registered, then: # 1) SOFT_DISABLED_BIT was cleared; # 2) trace_buffered_event_disable() was called first time; echo 1 > events/initcall/initcall_finish/enable # 3. Try to call into cmdline_proc_show(), then SOFT_DISABLED_BIT was # set again!!! cat /proc/cmdline # 4. Unregister the 'disable_event' command, then: # 1) SOFT_DISABLED_BIT was cleared again; # 2) trace_buffered_event_disable() was called second time!!! echo '!cmdline_proc_show:disable_event:initcall:initcall_finish' > \ set_ftrace_filter ``` To fix it, IIUC, we can change to call trace_buffered_event_enable() at fist time soft-mode enabled, and call trace_buffered_event_disable() at last time soft-mode disabled. | ||||

| CVE-2023-54188 | 1 Linux | 1 Linux Kernel | 2025-12-31 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: dmaengine: apple-admac: Fix 'current_tx' not getting freed In terminate_all we should queue up all submitted descriptors to be freed. We do that for the content of the 'issued' and 'submitted' lists, but the 'current_tx' descriptor falls through the cracks as it's removed from the 'issued' list once it gets assigned to be the current descriptor. Explicitly queue up freeing of the 'current_tx' descriptor to address a memory leak that is otherwise present. | ||||

| CVE-2023-54193 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: net/sched: cls_api: remove block_cb from driver_list before freeing Error handler of tcf_block_bind() frees the whole bo->cb_list on error. However, by that time the flow_block_cb instances are already in the driver list because driver ndo_setup_tc() callback is called before that up the call chain in tcf_block_offload_cmd(). This leaves dangling pointers to freed objects in the list and causes use-after-free[0]. Fix it by also removing flow_block_cb instances from driver_list before deallocating them.

| In the Linux kernel, the following vulnerability has been resolved: igc: Fix Kernel Panic during ndo_tx_timeout callback The Xeon validation group has been carrying out some loaded tests with various HW configurations, and they have seen some transmit queue time out happening during the test. This will cause the reset adapter function to be called by igc_tx_timeout(). Similar race conditions may arise when the interface is being brought down and up in igc_reinit_locked(), an interrupt being generated, and igc_clean_tx_irq() being called to complete the TX. When the igc_tx_timeout() function is invoked, this patch will turn off all TX ring HW queues during igc_down() process. TX ring HW queues will be activated again during the igc_configure_tx_ring() process when performing the igc_up() procedure later. This patch also moved existing igc_disable_tx_ring_hw() to avoid using forward declaration.

| CVE-2023-54201 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fix wrong resources deallocation order When trying to destroy QP or CQ, we first decrease the refcount and potentially free memory regions allocated for the object and then request the device to destroy the object. If the device fails, the object isn't fully destroyed so the user/IB core can try to destroy the object again which will lead to underflow when trying to decrease an already zeroed refcount. Deallocate resources in reverse order of allocating them to safely free them. | ||||
| CVE-2023-54178 | 1 Linux | 1 Linux Kernel | 2025-12-31 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: of: unittest: fix null pointer dereferencing in of_unittest_find_node_by_name() when kmalloc() fail to allocate memory in kasprintf(), name or full_name will be NULL, strcmp() will cause null pointer dereference. | ||||
| CVE-2023-54202 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/i915: fix race condition UAF in i915_perf_add_config_ioctl Userspace can guess the id value and try to race oa_config object creation with config remove, resulting in a use-after-free if we dereference the object after unlocking the metrics_lock. For that reason, unlocking the metrics_lock must be done after we are done dereferencing the object. [tursulin: Manually added stable tag.] (cherry picked from commit 49f6f6483b652108bcb73accd0204a464b922395) | ||||
| CVE-2023-54167 | 1 Linux | 1 Linux Kernel | 2025-12-31 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: m68k: mm: Move initrd phys_to_virt handling after paging_init() When booting with an initial ramdisk on platforms where physical memory does not start at address zero (e.g. on Amiga): initrd: 0ef0602c - 0f800000 Zone ranges: DMA [mem 0x0000000008000000-0x000000f7ffffffff] Normal empty Movable zone start for each node Early memory node ranges node 0: [mem 0x0000000008000000-0x000000000f7fffff] Initmem setup node 0 [mem 0x0000000008000000-0x000000000f7fffff] Unable to handle kernel access at virtual address (ptrval) Oops: 00000000 Modules linked in: PC: [<00201d3c>] memcmp+0x28/0x56 As phys_to_virt() relies on m68k_memoffset and module_fixup(), it must not be called before paging_init(). Hence postpone the phys_to_virt handling for the initial ramdisk until after calling paging_init(). While at it, reduce #ifdef clutter by using IS_ENABLED() instead. | ||||
| CVE-2023-54203 | 1 Linux | 1 Linux Kernel | 2025-12-31 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix slab-out-of-bounds in init_smb2_rsp_hdr When smb1 mount fails, KASAN detect slab-out-of-bounds in init_smb2_rsp_hdr like the following one. For smb1 negotiate(56bytes) , init_smb2_rsp_hdr() for smb2 is called. The issue occurs while handling smb1 negotiate as smb2 server operations. Add smb server operations for smb1 (get_cmd_val, init_rsp_hdr, allocate_rsp_buf, check_user_session) to handle smb1 negotiate so that smb2 server operation does not handle it.
