Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Linux kernel amdgpu display driver (drm/amd/display) is affected in several version ranges, starting from version 6.0 and in some backported branches. The plane reset function freed the old state before allocating a new one, so a failed memory allocation could leave a dangling pointer to freed memory. The source gives few details on how this could be triggered or what an attacker could do with it. Upgrade to a fixed kernel version: 6.1.191 or later in the 6.1 series, 6.6.160 or later in the 6.6 series, 6.12.114 or later in the 6.12 series, or 6.18.57 or later in the 6.18 series.
