GHSA-2W74-HFC7-29W5

Vulnerability from github – Published: 2024-11-08 06:30 – Updated: 2024-11-27 21:32

Details

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

drm/panthor: Fix access to uninitialized variable in tick_ctx_cleanup()

The group variable can't be used to retrieve ptdev in our second loop, because it points to the previously iterated list_head, not a valid group. Get the ptdev object from the scheduler instead.

Severity ?

5.5 (Medium)
