Technical Description

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: idxd: Fix oops during rmmod on single-CPU platforms

During the removal of the idxd driver, registered offline callback is

invoked as part of the clean up process. However, on systems with only

one CPU online, no valid target is available to migrate the

perf context, resulting in a kernel oops:

BUG: unable to handle page fault for address: 000000000002a2b8

#PF: supervisor write access in kernel mode

#PF: error_code(0x0002) - not-present page

PGD 1470e1067 P4D 0
