https://notcve.org/view.php?id=CVE-2022-44034
An issue was discovered in the Linux kernel through 6.0.6. drivers/char/pcmcia/scr24x_cs.c has a race condition and resultant use-after-free if a physically proximate attacker removes a PCMCIA device while calling open(), aka a race condition between scr24x_open() and scr24x_remove(). Se descubrió un problema en el kernel de Linux hasta la versión 6.0.6. drivers/char/pcmcia/scr24x_cs.c tiene una condición de ejecución y Use-After-Free resultante si un atacante físicamente cercano elimina un dispositivo PCMCIA mientras llama a open(), también conocido como una condición de ejecución entre scr24x_open() y scr24x_remove(). • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9b12f050c76f090cc6d0aebe0ef76fed79ec3f15 https://lore.kernel.org/lkml/20220916050333.GA188358%40ubuntu https://lore.kernel.org/lkml/20220919101825.GA313940%40ubuntu • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2022-3344
https://notcve.org/view.php?id=CVE-2022-3344
A flaw was found in the KVM's AMD nested virtualization (SVM). A malicious L1 guest could purposely fail to intercept the shutdown of a cooperative nested guest (L2), possibly leading to a page fault and kernel panic in the host (L0). Se ha encontrado un fallo en la virtualización anidada AMD (SVM) de KVM. Un huésped L1 malicioso podría fallar a propósito para interceptar el apagado de un huésped anidado cooperativo (L2), posiblemente conllevando a una falla de página y pánico del kernel en el host (L0) • https://bugzilla.redhat.com/show_bug.cgi?id=2130278 https://lore.kernel.org/lkml/20221020093055.224317-5-mlevitsk%40redhat.com/T • CWE-440: Expected Behavior Violation •
CVE-2022-3649 – Linux Kernel BPF inode.c nilfs_new_inode use after free
https://notcve.org/view.php?id=CVE-2022-3649
A vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is the function nilfs_new_inode of the file fs/nilfs2/inode.c of the component BPF. The manipulation leads to use after free. It is possible to launch the attack remotely. • https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git/commit/?id=d325dc6eb763c10f591c239550b8c7e5466a5d09 https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://lists.debian.org/debian-lts-announce/2022/12/msg00034.html https://security.netapp.com/advisory/ntap-20230214-0009 https://vuldb.com/?id.211992 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-416: Use After Free •
CVE-2022-3586 – Linux Kernel Net Scheduler Use-After-Free Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2022-3586
A flaw was found in the Linux kernel’s networking code. A use-after-free was found in the way the sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed) into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a denial of service. Se ha encontrado un fallo en el código de red del kernel de Linux. Ha sido encontrado un uso de memoria previamente liberada en la forma en que la función sch_sfb enqueue usó el campo cb del búfer de socket (SKB) después de que el mismo SKB había sido puesto en cola (y liberado) en un qdisc hijo. • https://github.com/torvalds/linux/commit/9efd23297cca https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://www.zerodayinitiative.com/advisories/upcoming • CWE-416: Use After Free •
