CVE-2024-38637

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: greybus: luces: verificar el retorno de get_channel_from_mode Si no se encuentra el canal para el nodo dado, devolvemos nulo de get_channel_from_mode. Asegúrese de validar el puntero de retorno antes de usarlo en dos de los lugares que faltan.

In the Linux kernel, the following vulnerability has been resolved: greybus: lights: check return of get_channel_from_mode If channel for the given node is not found we return null from get_channel_from_mode. Make sure we validate the return pointer before using it in two of the missing places. This was originally reported in [0]: Found by Linux Verification Center (linuxtesting.org) with SVACE.

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.
