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

Description The Linux kernel contains a flaw within the ipu-bridge module where a null pointer dereference can occur during the parsing of SSDB/PLD warnings in the ipu bridge parse rotation() and ipu bridge parse orientation() functions. This happens when sensor->adev is not yet set, leading to a crash if warning messages about unknown values are triggered. The issue is resolved by setting sensor->adev earlier in the process, using a borrowed reference.

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