CVE-2026-99095

The Linux kernel contains a vulnerability in the drm/vc4 driver where the hangcheck timer and job_done_work are not properly stopped during teardown. Specifically, vc4_irq_disable() fails to cancel these tasks, leading to situations where a timer reads V3D registers through a NULL pointer and lat...

UBUNTU-CVE-2026-98946

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Disable the V3D interrupt across runtime suspend vc4irqdisable masks the V3D interrupt sources and then calls synchronizeirq before the V3D is powered down. However, by itself, this is not enough to quiesce the interrupt...

UBUNTU-CVE-2026-98970

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Free the BO cache size list on teardown vc4bocachedestroy purges the cached BOs but never frees the size list, leaking it on every unbind...

CVE-2026-98970

The Linux kernel contains a memory leak vulnerability within the drm/vc4 component. Specifically, the vc4_bo_cache_destroy() function purges cached Buffer Objects (BOs) but fails to free the size list , resulting in a memory leak every time an unbind occurs. The provided documents do not include ...

CVE-2026-98946

The Linux kernel contains a vulnerability in the drm/vc4 driver where the V3D interrupt is not properly quiesced during runtime suspend. On RPi 0-3 , the use of the ARMCTRL interrupt controller allows a CPU to acknowledge an interrupt without it becoming visible to synchronize_irq(). This can cau...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Do not check if plane-state-fb == state-fb Currently, when using non-blocking commits, the following kernel warnings can be observed: 110.908514 ------------ Cut here ------------ 110.908529 refcountt: Underflow; Use aft...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Zero the Tile State Data Array TSDA before each BIN job. The binner BO consists of a single 16MB buffer, divided into 512KB slots. These slots are allocated to jobs at submission time and are recycled as jobs complete. T...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Fixed a memory leak in the BO array when it is in a hung state. The BO array that is in a hung state is allocated separately using kzalloc in vc4savehangstate, but it is never freed using vc4freehangstate. Add the missin...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: The platformgetirqbyname function returns an integer. If an error occurs, platformgetirqbyname will return a negative value. Therefore, this value should be checked instead of being passed directly into...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: The overflow slot size is specified in BPOS, rather than the entire binner BO size. The vc4overflowmemwork function points BPOA to a 512KB slot within the 16MB binner BO. However, the size of the entire BO is written to...
