CVE-2026-74491

The CVE-2026-74491 entry describes a Linux kernel vulnerability where a NULL bus dereference could occur in the PCI range parser (of_pci_range_parser_one) due to the bus matching rework: of_match_bus() could return NULL for nodes with ranges/dma-ranges but no local #address-cells. The fix rejects...

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 ...

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: bound DMA command body size against suffix pointer vmwcmddma locates the DMA suffix at unsigned long &cmd-body + header-size - sizeofsuffix without checking that header-size is large enough to contain both cmd-body an...

CVE-2026-74443

CVE-2026-74443 affects the Linux kernel DRM/vmwgfx path. The issue in vmw_cmd_dma() computes the DMA suffix location without ensuring header->size can contain both body and suffix, allowing an undersized header to underflow the suffix pointer and later overwrite verified fields of a relocated ...

CVE-2026-74440

Summary: CVE-2026-74440 affects Linux kernel DRM/XE, where a user job could race with kernel operations on external buffer objects (BOs) due to an incomplete dependency model. Root cause: during xe_exec_ioctl(), only the VM’s dma-resv KERNEL slot was added as a dependency, omitting external BOs (...
