UBUNTU-CVE-2026-74423

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix leak when pinning ubuf pages When pinuserpagesfast returns fewer pages than requested, the pages that were successfully pinned are not released, leading to a leak. Fix this by unpinning any partially pinned pag...

CVE-2026-72332

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Prevent PM resume deadlock in hwctxsyncdebugbo amdxdnahwctxsyncdebugbo invokes the hardware hwctxsyncdebugbo callback while holding xdna-devlock. The callback may call amdxdnacmdsubmit, which in turn calls...

UBUNTU-CVE-2026-74419

CVE-2026-74419

The CVE-2026-74419 issue affects the Linux kernel in accel/amdxdna: copy_to_user() could return more data than the user buffer, potentially exposing more data or failing when the app buffer is smaller. The root cause is not clearly detailed beyond “adjust size for copy_to_user()” and that the amo...
