CVE-2026-53140

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

drm/v3d: Fix vaddr leak when indirect CSD has zeroed workgroups

v3d_rewrite_csd_job_wg_counts_from_indirect() maps both the indirect buffer and the workgroup buffer and is expected to release them before returning. When any of the workgroup counts read from the buffer is zero, the function bailed out early and skipped the cleanup, leaking the vaddr mappings of both BOs.

Jump to the cleanup path instead of returning directly, so the mappings are always dropped.
