CVE-2024-53133

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Controlar el error de asignación de dml para evitar un bloqueo [Por qué] En el caso de que una asignación de dml falle por cualquier motivo, los contextos dml del estado actual ya no serían válidos. Luego, las llamadas posteriores a dc_state_copy_internal realizarían una copia superficial de la memoria no válida y, si se liberara el nuevo estado, se produciría una doble liberación. [Cómo] Restablecer los punteros dml en new_state a NULL y evitar un puntero no válido (seleccionado de el commit bcafdc61529a48f6f06355d78eb41b3aeda5296c)

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Handle dml allocation failure to avoid crash [Why] In the case where a dml allocation fails for any reason, the current state's dml contexts would no longer be valid. Then subsequent calls dc_state_copy_internal would shallow copy invalid memory and if the new state was released, a double free would occur. [How] Reset dml pointers in new_state to NULL and avoid invalid pointer (cherry picked from commit bcafdc61529a48f6f06355d78eb41b3aeda5296c)

Attila Szász discovered that the HFS+ file system implementation in the Linux Kernel contained a heap overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted, could cause a denial of service or possibly execute arbitrary code. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
