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...
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...
CVE-2026-74454
CVE-2026-74454 affects the Linux kernel driv3rs/drm vc4 by correcting how the overflow slot size is written during binner memory handling. The issue arises when vc4_overflow_mem_work() sets BPOA to a 512KB slot but BPOS stores the size of the entire 16MB binner BO, enabling the PTB to write tile ...

CVE-2026-74453
CVE-2026-74453 (Linux kernel, drm/vc4) : The issue arises in the VC4 tile binning path where the Tile State Data Array (TSDA) for a job’s tile set is left in the binner’s slot between submissions. A 16 MB binner buffer is split into 512 KB slots; TSDA is at the start of each slot and is used by h...

CVE-2026-68303
The CVE-2026-68303 entry describes a Linux kernel fix in drm/vc4: hvs/v3d where unbind functions used dev_get_drvdata(master). When vc4-drm is removed before dependent drivers, vc4_hvs_unbind/vc4_v3d_unbind could dereference a freed pointer. The remediation is to use the data pointer passed to th...
