NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150500_55_124-default package and not the kernel-livepatch-5_14_21-150500_55_124-default package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

drm/msm/dpu: check for null return of devm_kzalloc() in dpu_writeback_init()

Because of the possilble failure of devm_kzalloc(), dpu_wb_conn might be NULL and will cause null pointer dereference later.

Therefore, it might be better to check it and directly return -ENOMEM.
