CVE-2024-35940

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: pstore/zone: agregue una verificación de puntero null a psz_kmsg_read kasprintf() devuelve un puntero a la memoria asignada dinámicamente que puede ser NULL en caso de falla. Asegúrese de que la asignación haya sido exitosa verificando la validez del puntero.

In the Linux kernel, the following vulnerability has been resolved: pstore/zone: Add a null pointer check to the psz_kmsg_read kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. Ensure the allocation was successful by checking the pointer validity.

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. It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code.
