https://notcve.org/view.php?id=CVE-2022-43750
drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-space client to corrupt the monitor's internal memory. El archivo drivers/usb/mon/mon_bin.c en usbmon en el kernel de Linux versiones anteriores a 5.19.15 y versiones 6.x anteriores a 6.0.1, permite que un cliente del espacio de usuario corrompa la memoria interna del monitor An out-of-bounds memory write flaw in the Linux kernel’s USB Monitor component was found in how a user with access to the /dev/usbmon can trigger it by an incorrect write to the memory of the usbmon. This flaw allows a local user to crash or potentially escalate their privileges on the system. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.19.15 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.0.1 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a659daf63d16aa883be42f3f34ff84235c302198 https://github.com/torvalds/linux/commit/a659daf63d16aa883be42f3f34ff84235c302198 https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://lists.debian.org/debian-lts-announce/2022/12/msg00034.html https://access.redhat.com/security/cve • CWE-787: Out-of-bounds Write •

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 •
