| Assigner | Linux |
| Source Priority | CVE Program / NVD first with legacy fallback |

| Description | In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Guard management mailbox channel cleanup against NULL pointer
The management mailbox channel cleanup helpers can be called from
error handling paths when mgmt_chann has already been destroyed.
Add NULL checks to xdna_mailbox_free_channel() and
xdna_mailbox_stop_channel() so the cleanup path safely returns instead
of dereferencing a NULL mailbox channel pointer. |
