Description OSIDB Bzimport 2026-05-27 15:13:06 UTC
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.
