Description

In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Reject invalid indirect BO handle in indirect CSD setup v3d_get_cpu_indirect_csd_params() looks up the indirect buffer object from a userspace-supplied handle but never checks the result. A bogus or stale handle makes drm_gem_object_lookup() return NULL, which is then stored in info->indirect and only dereferenced later when the indirect CSD job runs, turning a userspace mistake into a NULL pointer dereference in the kernel. Bail out with -ENOENT as soon as the lookup fails, so the bad handle is rejected at submission time.

Affected products

• Linux kernel: 6.8 — fixed in 7.2

How to fix

Upgrade to a fixed version: Linux kernel 7.2. Check the vendor advisory for mitigations.
