https://notcve.org/view.php?id=CVE-2021-44733
A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11. This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object. Se presenta un uso de memoria previamente liberada en el archivo drivers/tee/tee_shm.c en el subsistema TEE en el kernel de Linux versiones hasta 5.15.11. Esto ocurre debido a una condición de carrera en tee_shm_get_from_id durante un intento de liberar un objeto de memoria compartida A use-after-free flaw in the Linux kernel TEE (Trusted Execution Environment) subsystem was found in the way user calls ioctl TEE_IOC_OPEN_SESSION or TEE_IOC_INVOKE. A local user could use this flaw to crash the system or escalate their privileges on the system. • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=dfd0743f1d9ea76931510ed150334d571fbab49d https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/drivers/tee/tee_shm.c https://github.com/pjlantz/optee-qemu/blob/main/README.md https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lore.kernel.org/lkml/20211215092501.1861229-1-jens.wiklander%40linaro.org https://security.netapp.com/advisory/ntap-20220114-0003 https://www.debian. • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-908: Use of Uninitialized Resource •

stab_xcoff_builtin_type in stabs.c in GNU Binutils through 2.37 allows attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact, as demonstrated by an out-of-bounds write. NOTE: this issue exists because of an incorrect fix for CVE-2018-12699. La función stab_xcoff_builtin_type en el archivo stabs.c en GNU Binutils versiones hasta 2.37, permite a atacantes causar una denegación de servicio (desbordamiento de búfer basado en la pila) o posiblemente tener otro impacto no especificado, como lo demuestra una escritura fuera de límites.
