CVE-2023-53322 is a use-after-free vulnerability in the Linux kernel SCSI qla2xxx driver’s remote-port termination handling. The terminate_rport_io() path can return before all outstanding I/O operations have returned to the upper layer. During final cleanup, upper-layer resources can consequently be freed while the qla2xxx driver or hardware still retains references to them. The condition is particularly relevant to FCP-2 devices, where I/O may remain in hardware following a cable pull because the firmware session is not torn down at the initial event. The fix waits for outstanding I/O to return before releasing associated resources.
