EUVD-2026-86976

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: reject a command chain that carries no commands A chain whose commandcount is zero passes the payload length check, because structsizepayload, data, 0 is just the header. The fill loop then does not run, so offset...

CVE-2026-98145

The Linux kernel contains a vulnerability in the accel/amdxdna driver where a command chain with a command_count of zero improperly passes payload length checks. Because the struct_size calculation only accounts for the header, the fill loop is skipped, resulting in the submission of a zero-lengt...

CVE-2026-98142

The Linux kernel contains a vulnerability in the cirrus-qemu driver where it fails to verify that the PCI BAR0 resource size matches the expected CIRRUS_VRAM_SIZE (4 MB) during the probe process. If a device with a BAR0 smaller than 4 MB is bound, the driver may allow the creation of framebuffers...

CVE-2026-98085

The Linux kernel contains a vulnerability in the BPF precision backtracking mechanism affecting BPF_LD | BPF_{IND,ABS} instructions. The root cause is that the backtrack_insn() function fails to handle the implicit exit case from a subprogram. Specifically, it does not call bt_subprog_enter() whe...
