Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw in the drm/msm/dpu subsystem where a failure of devm kzalloc() could lead to a null pointer dereference in the dpu writeback init() function. Specifically, if devm kzalloc() fails, dpu wb conn might be NULL, causing a subsequent null pointer dereference. The issue can be addressed by checking the return value of devm kzalloc() and returning -ENOMEM if it fails.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
