CVE: CVE-2022-48653
Published: 2024-04-28
Description: In the Linux kernel, the following vulnerability has been resolved:

ice: Don't double unplug aux on peer initiated reset

In the IDC callback that is accessed when the aux drivers request a reset,
the function to unplug the aux devices is called.  This function is also
called in the ice_prepare_for_reset function. This double call is causing
a "scheduling while atomic" BUG.
