      "title": "scsi: qla2xxx: Avoid double completion in async IOCB timeout",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Avoid double completion in async IOCB timeout\n\nqla2x00_async_iocb_timeout() tries to abort a timed-out async IOCB. When\nqla24xx_async_abort_cmd() fails, both the SRB_LOGIN_CMD path and the\nSRB_CTRL_VP/default path scan outstanding_cmds[] for the SRB and then\ncall sp->done(sp, QLA_FUNCTION_TIMEOUT) unconditionally, without checking\nwhether the SRB was actually found and removed.\n\nIf the response ISR completes the same handle first, it removes the SRB\nunder qp_lock_ptr and runs sp->done() -> complete(sp->comp). The\nsubmitter qla24xx_control_vp() wakes from wait_for_completion(), clears\nsp->comp, drops its reference and returns, reclaiming the on-stack\ncompletion. The timer reference keeps the SRB alive across the timeout\nhandler, but not the submitter's stack. The timeout then issues a second\nsp->done() -> qla_ctrlvp_sp_done(), which evaluates \"if (sp->comp)\ncomplete(sp->comp)\"; with the pointer loaded before the submitter's NULL\nstore, complete() writes into the freed stack frame, a use-after-free.\n\nTrack whether this path removed the SRB from outstanding_cmds and only\ncall sp->done() when it did, so the command is completed exactly once by\nwhichever path owns it. This mirrors the sp_found guard already used in\nqla24xx_abort_iocb_timeout().",
