Polychrome This is a example on how to embed a payload into a compute shader. The payload is encrypted and decrypted on the GPU. This is not by any means a complete implementation it misses crucial OPSEC considerations. Usage Generate a payload using your preferred method i used the classic...
Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: virglrenderer (UTSA-2026-093021)
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-093021 advisory. A NULL pointer dereference in vrendrenderer.c in virglrenderer through 0.8.1 allows attackers to cause a denial of service via commands that attempt to launch a grid...
CVE-2026-53139
A flaw was found in the Linux kernel's graphics driver for Broadcom V3D VideoCore V GPUs. This vulnerability occurs when a compute shader dispatch CSD is initiated with zero workgroup counts, which the hardware could misinterpret as a very large number. This misinterpretation could lead to...
SUSE CVE-2026-53139
In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Skip CSD when it has zeroed workgroups A compute shader dispatch encodes its workgroup counts in the CFG0..CFG2 registers. Kicking off a dispatch with a zero count in any of the three dimensions is invalid. First, the...

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-2026-53139

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...
