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.
AnalysisAI
A null pointer dereference vulnerability exists in the Linux kernel's AMD XDNA accelerator driver (accel/amdxdna) that can cause a kernel crash when userspace attempts to destroy a hardware context that has been automatically suspended. The vulnerability affects all Linux kernel versions with the vulnerable amdxdna driver code path; an unprivileged local user with access to the driver's ioctl interface can trigger a denial of service by issuing a destroy context command on a suspended context, causing the kernel to crash when accessing a NULL mailbox channel pointer. …
