Summary

In the Linux kernel, the drm/panthor driver has a use-after-free (UAF) vulnerability on kernel BO VA nodes. When the MMU is down, panthor_vm_unmap_range() may return an error, but the code does not continue cleanup, leaving the va_node in drm_mm, leading to UAF when adjacent nodes are removed.

Risk Assessment

An attacker could exploit this vulnerability to access freed memory, potentially leading to system crashes or arbitrary code execution.

Recommendation

Apply the Linux kernel patch that continues cleanup even if panthor_vm_unmap_range() fails.

Original NVD description (English source)

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Fix UAF on kernel BO VA nodes If the MMU is down, panthor_vm_unmap_range() might return an error. We expect the page table to be updated still, and if the MMU is blocked, the rest of the GPU should be blocked too, so no risk of accessing physical memory returned to the system (which the current code doesn't cover for anyway). Proceed with the rest of the cleanup instead of bailing out and leaving the va_node inserted in the drm_mm, which leads to UAF when other adjacent nodes are removed from the drm_mm tree.
