CVE-2026-46310
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.
Affected versions
Linux kernel versions
6.17
and later are affected. Fixed in
