|---|---|---|---|---|---|
| CVE-2021-3975 | 5 Canonical, Debian, Fedoraproject and 2 more | 14 Ubuntu Linux, Debian Linux, Fedora and 11 more | 2024-11-21 | N/A | 6.5 MEDIUM |
| A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash. | |||||

| A flaw was found in the Linux kernel. A use-after-free vulnerability in the NFC stack can lead to a threat to confidentiality, integrity, and system availability. | |||||
| CVE-2021-3752 | 6 Debian, Fedoraproject, Linux and 3 more | 27 Debian Linux, Fedora, Linux Kernel and 24 more | 2024-11-21 | 7.9 HIGH | 7.1 HIGH |
| A use-after-free flaw was found in the Linux kernel’s Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the system or escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. | |||||
| CVE-2021-3750 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-11-21 | 4.6 MEDIUM | 8.2 HIGH |
| A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions (such as reset) while the device is still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code within the context of the QEMU process on the host. This flaw affects QEMU versions before 7.0.0. | |||||
| CVE-2021-3748 | 5 Canonical, Debian, Fedoraproject and 2 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-11-21 | 6.9 MEDIUM | 7.5 HIGH |
| A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process. | |||||
| CVE-2021-3738 | 1 Samba | 1 Samba | 2024-11-21 | 6.5 MEDIUM | 8.8 HIGH |
| In DCE/RPC it is possible to share the handles (cookies for resource state) between multiple connections via a mechanism called 'association groups'. These handles can reference connections to our sam.ldb database. However while the database was correctly shared, the user credentials state was only pointed at, and when one connection within that association group ended, the database would be left pointing at an invalid 'struct session_info'. The most likely outcome here is a crash, but it is possible that the use-after-free could instead allow different user state to be pointed at and this might allow more privileged access. | |||||
| CVE-2021-3715 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 7.2 HIGH | 7.8 HIGH |
| A flaw was found in the "Routing decision" classifier in the Linux kernel's Traffic Control networking subsystem in the way it handled changing of classification filters, leading to a use-after-free condition. This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. | |||||
| CVE-2021-3700 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2024-11-21 | 4.4 MEDIUM | 6.4 MEDIUM |
| A use-after-free vulnerability was found in usbredir in versions prior to 0.11.0 in the usbredirparser_serialize() in usbredirparser/usbredirparser.c. This issue occurs when serializing large amounts of buffered write data in the case of a slow or blocked destination. | |||||
| CVE-2021-3640 | 5 Canonical, Debian, Fedoraproject and 2 more | 20 Ubuntu Linux, Debian Linux, Fedora and 17 more | 2024-11-21 | 6.9 MEDIUM | 7.0 HIGH |
| A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system. | |||||
| CVE-2021-3543 | 3 Fedoraproject, Nitro Enclaves Project, Redhat | 3 Fedora, Nitro Enclaves, Enterprise Linux | 2024-11-21 | 7.2 HIGH | 6.7 MEDIUM |
| A flaw null pointer dereference in the Nitro Enclaves kernel driver was found in the way that Enclaves VMs forces closures on the enclave file descriptor. A local user of a host machine could use this flaw to crash the system or escalate their privileges on the system. | |||||
