https://notcve.org/view.php?id=CVE-2024-35789
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes When moving a station out of a VLAN and deleting the VLAN afterwards, the fast_rx entry still holds a pointer to the VLAN's netdev, which can cause use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx after the VLAN change. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: mac80211: comprobar/borrar fast rx para cambios de VLAN que no sean 4addr sta Al mover una estación fuera de una VLAN y eliminar la VLAN después, la entrada fast_rx todavía contiene un puntero a netdev de la VLAN, lo que puede causar errores de uso después de la liberación. Solucione este problema llamando inmediatamente a ieee80211_check_fast_rx después del cambio de VLAN. • https://git.kernel.org/stable/c/ea9a0cfc07a7d3601cc680718d9cff0d6927a921 https://git.kernel.org/stable/c/be1dd9254fc115321d6fbee042026d42afc8d931 https://git.kernel.org/stable/c/e8b067c4058c0121ac8ca71559df8e2e08ff1a7e https://git.kernel.org/stable/c/c8bddbd91bc8e42c961a5e2cec20ab879f21100f https://git.kernel.org/stable/c/7eeabcea79b67cc29563e6a9a5c81f9e2c664d5b https://git.kernel.org/stable/c/6b948b54c8bd620725e0c906e44b10c0b13087a7 https://git.kernel.org/stable/c/2884a50f52313a7a911de3afcad065ddbb3d78fc https://git.kernel.org/stable/c/e8678551c0243f799b4859448781cbec1 •

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix bounds check for dcn35 DcfClocks [Why] NumFclkLevelsEnabled is used for DcfClocks bounds check instead of designated NumDcfClkLevelsEnabled. That can cause array index out-of-bounds access. [How] Use designated variable for dcn35 DcfClocks bounds check. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amd/display: Corrige la verificación de límites para dcn35 DcfClocks [Por qué] NumFclkLevelsEnabled se usa para la verificación de límites de DcfClocks en lugar del designado NumDcfClkLevelsEnabled.

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: fix stale locked mutex in nouveau_gem_ioctl_pushbuf If VM_BIND is enabled on the client the legacy submission ioctl can't be used, however if a client tries to do so regardless it will return an error. In this case the clients mutex remained unlocked leading to a deadlock inside nouveau_drm_postclose or any other nouveau ioctl call. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/nouveau: corrige el mutex bloqueado obsoleto en nouveau_gem_ioctl_pushbuf. Si VM_BIND está habilitado en el cliente, el ioctl de envío heredado no se puede usar; sin embargo, si un cliente intenta hacerlo independientemente, lo hará. devolver un error.
