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-2026-98144

A memory leak vulnerability exists in the Linux kernel within the accel/amdxdna component. The amdxdna_cmd_set_error() function takes a reference to the first BO of a command chain and intends to drop it at the end of the function. However, a failure path during the mapping process returns early ...

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...

CVE-2026-89978

CVE-2026-89978 affects the Linux kernel accel/amdxdna driver (AMD NPU). The SYNC_BO ioctl does not validate that the requested size is non-zero, so a zero-byte request reaches drm_clflush_virt_range(), which unconditionally calls clflushopt(end - 1). For an empty range this dereferences the guard...
