CVE-2026-53139

CVE-2026-53139 concerns the Linux kernel drm/v3d path where a compute shader dispatch with zeroed workgroup counts (CFG0..CFG2) could be mishandled; the fix ensures the indirect CSD job is not submitted when any dimension is zero, causing the dispatch to complete as a no-op. Connected sources sho...

CVE-2026-53140

The CVE-2026-53140 issue pertains to the Linux kernel drm/v3d driver. A fault in v3d_rewrite_csd_job_wg_counts_from_indirect() maps both the indirect buffer and the workgroup buffer and, if any workgroup count read from the buffer is zero, the cleanup is skipped on an early exit, leaking the virt...

CVE-2026-53141

The CVE-2026-53141 issue affects the Linux kernel drm/v3d driver’s global performance monitor reference counting.
