CVE-2026-98146

The Linux kernel contains a vulnerability in the accel/amdxdna component. The struct amdxdna_cmd_chain utilizes a flexible array annotated with __counted_by(command_count). Because this structure resides in shared AMDXDNA_BO_SHARE memory, userspace can concurrently modify command_count. If an att...

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...

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...
