GHSA-CH5R-R49P-5XQV
Vulnerability from github – Published: 2025-12-24 12:30 – Updated: 2026-10-15 03:35In the Linux kernel, the following vulnerability has been resolved:
scsi: smartpqi: Fix device resources accessed after device removal
Correct possible race conditions during device removal.
Previously, a scheduled work item to reset a LUN could still execute after the device was removed, leading to use-after-free and other resource access issues.
This race condition occurs because the abort handler may schedule a LUN reset concurrently with device removal via sdev_destroy(), leading to use-after-free and improper access to freed resources.
-
Check in the device reset handler if the device is still present in the controller's SCSI device list before running; if not, the reset is skipped.
-
Cancel any pending TMF work that has not started in sdev_destroy().
-
Ensure device freeing in sdev_destroy() is done while holding the LUN reset mutex to avoid races with ongoing resets.
