CVE-2023-53322

Linux Linux, linux kernel

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Wait for io return on terminate rport System crash due to use after free. Current code allows terminate_rport_io to exit before making sure all IOs has returned. For FCP-2 device, IO's can hang on in HW because driver has not tear down the session in FW at first sign of cable pull. When dev_loss_tmo timer pops, terminate_rport_io is called and upper layer is about to free various resources. Terminate_rport_io trigger qla to do the final cleanup, but the cleanup might not be fast enough where it leave qla stil...

Full remediation guide
  1. 1
    Identify

    Confirm that Linux Linux, linux kernel and an affected version are present.

  2. 2
    Prioritize

    Combine exploitation signals with asset exposure and business criticality.

  3. 3
    Remediate

    Follow the vendor advisory or supported update path and preserve rollback options.

  4. 4
    Verify

    Recheck the version, service health, access paths, and relevant logs.
