12 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/radeon: fix UBSAN warning in kv_dpm.c Adds bounds check for sumo_vid_mapping_entry. A vulnerability was found in the Linux kernel's DRM/Radeon driver, specifically in the sumo_vid_mapping_entry within the kv_dpm.c file. Insufficient bounds checking can lead to memory corruption. Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a den... • https://git.kernel.org/stable/c/80ea2c129c76a4159a93efeaef4385b6c964dfac • CWE-787: Out-of-bounds Write •

Undo the modifications made in commit d410ee5109a1 ("ACPICA: avoid "Info: mapping multiple BARs. Your kernel is fine.""). The initial purpose of this commit was to stop memory mappings for operation regions from overlapping page boundaries, as it can trigger warnings if different page attributes are present. • https://git.kernel.org/stable/c/d410ee5109a1633a686a5663c6743a92e1181f9b • CWE-476: NULL Pointer Dereference •
