In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Adjust VSDB parser for replay feature
At some point, the IEEE ID identification for the replay check in the
AMD EDID was added. However, this check causes the following
out-of-bounds issues when using KASAN:
[ 27.804016] BUG: KASAN: slab-out-of-bounds in amdgpu_dm_update_freesync_caps+0xefa/0x17a0 [amdgpu]

[ 27.821268] ==================================================================
This is caused because the ID extraction happens outside of the range of
the edid lenght. This commit addresses this issue by considering the
amd_vsdb_block size.

Summary | (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Ajustar el analizador VSDB para la función de reproducción En algún momento, se agregó la identificación IEEE ID para la comprobación de reproducción en AMD EDID. Sin embargo, esta comprobación provoca los siguientes problemas fuera de los límites al utilizar KASAN: [ 27.804016] ERROR: KASAN: slab-out-of-bounds en amdgpu_dm_update_freesync_caps+0xefa/0x17a0 [amdgpu] [ 27.804788] Lectura de tamaño 1 en la dirección ffff8881647fdb00 por la tarea systemd-udevd/383 ...
