CVE-2026-72332: accel/amdxdna: Prevent PM resume deadlock in hwctx_sync_debug_bo()
In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Prevent PM resume deadlock in hwctxsyncdebugbo()
amdxdnahwctxsyncdebugbo() invokes the hardware hwctxsyncdebugbo() callback while holding xdna->devlock.
The callback may call amdxdnacmdsubmit(), which in turn calls amdxdnapmresumeget(). If the device is suspended, amdxdnapmresumeget() may synchronously execute amdxdnapmresume(), which also acquires xdna->devlock, resulting in a deadlock.
Avoid the deadlock by calling amdxdnapmresumeget() before holding xdna->devlock in both amdxdnahwctxsyncdebugbo() and amdxdnadrmconfighwctxioctl()
