Linux Kernel DRAM NULL Pointer Dereference Vulnerability
Description
In the Linux kernel, the following vulnerability has been resolved: drm/mst: Fix NULL pointer dereference at drm_dp_add_payload_part2 [Why] Commit: - commit 5aa1dfcdf0a4 ("drm/mst: Refactor the flow for payload allocation/removement") accidently overwrite the commit - commit 54d217406afe ("drm: use mgr->dev in drm_dbg_kms in drm_dp_add_payload_part2") which cause regression. [How] Recover the original NULL fix and remove the unnecessary input parameter 'state' for drm_dp_add_payload_part2(). (cherry picked from commit 4545614c1d8da603e57b60dd66224d81b6ffc305)
