CVE-2026-74454
A flaw was found in the Linux kernel's drm/vc4 component. An out-of-bounds write vulnerability exists where the graphics processing unit GPU driver incorrectly calculates memory allocation sizes. This allows the GPU to write data beyond its allocated memory region during out-of-memory events. Thi...
CVE-2026-74453
A flaw was found in the Linux kernel's drm/vc4 component. The graphics driver's binner buffer object BO reuses memory slots without properly clearing the Tile State Data Array TSDA. This allows the hardware to process stale data from previous jobs, leading to the creation of invalid command strea...
UBUNTU-CVE-2026-74454
In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Supply the overflow slot size in BPOS, not the whole bin BO size vc4overflowmemwork points BPOA at a 512KB slot inside the 16MB binner BO, but writes the size of the whole BO to BPOS. On every binner out-of-memory event...
UBUNTU-CVE-2026-74453
In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Zero the tile state data array before each BIN job The binner BO is a single 16MB buffer split into 512KB slots that are handed out to jobs at submission time and recycled as jobs complete, without ever being cleared. Ea...

Linux Distros Unpatched Vulnerability : CVE-2026-74453
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - drm/vc4: Zero the tile state data array before each BIN job The binner BO is a single 16MB buffer split into 512KB slots that are handed out to jobs at submissi...
CVE-2026-68445
A flaw was found in the Linux kernel's drm/vc4 component. This vulnerability allows a local user to bypass security validation for shader code. By manipulating memory permissions, an attacker could modify shader instructions after they have been deemed safe, potentially leading to unauthorized co...

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Prevent shader BO mappings from becoming writable vc4gemobjectmmap rejects a writable mapping of a validated shader BO, but leaves VMMAYWRITE set. Userspace can map the BO read-only and then turn it writable with mprotec...

CVE-2026-68445
CVE-2026-68445 (Linux kernel, drm/vc4) fixes a local breach where a validated shader BO could be mapped read-only and then upgraded to writable via mprotect(), bypassing the validator. The issue stems from vc4_gem_object_mmap() leaving VM_MAYWRITE set on the read-only path, allowing userspace to ...

CVE-2026-68233
A flaw was found in the drm/vc4 component of the Linux kernel. A logic error in the BO cache timer shutdown process allows the timer to be rearmed even after it has been destroyed. This can lead to work being queued again after teardown, potentially causing system instability or a denial of servi...
CVE-2026-68303
A flaw was found in the Linux kernel's drm/vc4 drivers, specifically in the hvs and v3d components. When these drivers are being removed, they attempt to access memory that has already been freed. This occurs because they try to retrieve driver data from a master device that is no longer availabl...
