Doc Text:
A flaw was found in the Linux kernel's media: renesas: vsp1 component. When unloading the module on generation 4 hardware, an incorrect cleanup function is called, leading to a NULL pointer dereference. This vulnerability can be triggered by a local attacker, potentially causing a system crash and resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-06-08 17:02:02 UTC 
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.
