Description OSIDB Bzimport 2026-03-25 11:03:14 UTC 
In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Fix crash when destroying a suspended hardware context

If userspace issues an ioctl to destroy a hardware context that has
already been automatically suspended, the driver may crash because the
mailbox channel pointer is NULL for the suspended context.

Fix this by checking the mailbox channel pointer in aie2_destroy_context()
before accessing it.
