CVE-2026-46310 Details
Description
In the Linux kernel, the following vulnerability has been resolved: media: renesas: vsp1: Fix NULL pointer deref on module unload When unloading the module on gen 4, we hit a NULL pointer dereference. This is caused by the cleanup code calling vsp1_drm_cleanup() where it should be calling vsp1_vspx_cleanup(). Fix this by checking the IP version and calling the drm or vspx function accordingly, the same way as the init code does.
A NULL pointer dereference vulnerability has been identified in the Linux kernel's VSP1 module for Generation 4. This issue occurs during the module unload process, where the cleanup code incorrectly calls the 'vsp1_drm_cleanup()' function instead of the appropriate 'vsp1_vspx_cleanup()' function. The error arises because the cleanup code does not properly check the IP version before calling the cleanup functions, leading to a crash when the module is unloaded.
The vulnerability has been fixed in the Linux kernel. Users should upgrade to the latest version where this issue has been addressed.
