Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-11 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

drm/vc4: Fix a memory leak in hang state error path

When vc4_save_hang_state() encounters an early return condition, it returns without freeing the previously allocated kernel_state, leaking memory.

Add the missing kfree() calls by consolidating the early return paths into a single place.

Severity ?

5.5 (Medium)
