What is CVE-2025-71308?
CVE-2025-71308 is a medium-severity vulnerability in Linux kernel, published on 27 May 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
