Machine-written summary

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

The Linux kernel's AMD display driver (drm/amd/display) is affected from version 4.15 until fixed in 6.1.191, 6.6.160, 6.12.114, or 6.18.57 and later in those series. A failed memory allocation during CRTC reset leaves a dangling pointer to freed memory. The source gives few details on attacker requirements or impact; upgrade to a fixed kernel for your branch.
