Description

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: Fix error pointers in dpu_plane_virtual_atomic_check The function dpu_plane_virtual_atomic_check was dereferencing pointers returned by drm_atomic_get_plane_state without checking for errors. This could lead to undefined behavior if the function returns an error pointer. This commit adds checks using IS_ERR to ensure that plane_state is valid before dereferencing them. Similar to commit da29abe71e16 ("drm/amd/display: Fix error pointers in amdgpu_dm_crtc_mem_type_changed"). Patchwork: https://patchwork.freedesktop.org/patch/643132/

Affected products

Linux kernel: from 6.14 before 6.14.4; 6.15-rc1, 6.15-rc2 — fixed in 6.14.4

How to fix

Upgrade to a fixed version: Linux kernel 6.14.4. Check the vendor advisory for mitigations.
