CVE-2022-49157
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix premature hw access after PCI error
After a recoverable PCI error has been detected and recovered, qla driver needs to check to see if the error condition still persist and/or wait for the OS to give the resume signal.
