kernel: accel/amdxdna: Fix potential NULL pointer dereference in context cleanup
    </Bugzilla>
    <CWE>CWE-476</CWE>
    <Details xml:lang="en:us" source="Mitre">
In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Fix potential NULL pointer dereference in context cleanup

aie_destroy_context() is invoked during error handling in
aie2_create_context(). However, aie_destroy_context() assumes that the
context's mailbox channel pointer is non-NULL. If mailbox channel
creation fails, the pointer remains NULL and calling aie_destroy_context()
can lead to a NULL pointer dereference.

In aie2_create_context(), replace aie_destroy_context() with a function
which request firmware to remove the context created previously.
    </Details>
    <Details xml:lang="en:us" source="Red Hat">
A flaw was found in the Linux kernel's accel/amdxdna module. During error handling in the `aie2_create_context()` function, the `aie_destroy_context()` function can be called when a mailbox channel pointer is unexpectedly null. This can lead to a NULL pointer dereference, potentially causing a system crash and resulting in a Denial of Service (DoS).
