CVE-2026-80577

A flaw was found in the Linux kernel's drm/panthor driver. When the panthorfwloadsectionentry function processes zero-sized firmware sections, it can leave a memory pointer uninitialized. Subsequent operations that attempt to access this uninitialized memory can lead to a null pointer dereference...

The vulnerability of the `panthor_kernel_bodestroy()` function in the `drivers/gpu/drm/panthor/panthor_gem.c` file of the Panthor driver (which provides DRM support for ARM Mali CSF-based graphics processors) in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the panthorkernelbodestroy function in the drivers/gpu/drm/panthor/panthorgem.c file of the Panthor driver which provides DRM support for ARM Mali CSF-based graphics processors in the Linux operating system is related to the reutilization of previously freed memory. Exploitin...

SUSE CVE-2026-74451
