Description OSIDB Bzimport 2026-01-13 16:02:52 UTC
In the Linux kernel, the following vulnerability has been resolved:

scsi: aic94xx: fix use-after-free in device removal path

The asd_pci_remove() function fails to synchronize with pending tasklets
before freeing the asd_ha structure, leading to a potential
use-after-free vulnerability.

When a device removal is triggered (via hot-unplug or module unload),
race condition can occur.

The fix adds tasklet_kill() before freeing the asd_ha structure,
ensuring all scheduled tasklets complete before cleanup proceeds.
