Description
A flaw was found in the Linux kernel's drm/v3d driver. This vulnerability occurs because a specific function, v3d_rewrite_csd_job_wg_counts_from_indirect(), does not correctly release virtual address mappings under certain conditions, specifically when workgroup counts are zero. This oversight results in a virtual address leak, which could potentially allow an attacker to gain sensitive information about the system's memory configuration.
