Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
scsi: aic94xx: fix use-after-free in device removal path<br />
<br />
The asd_pci_remove() function fails to synchronize with pending tasklets<br />
before freeing the asd_ha structure, leading to a potential<br />
use-after-free vulnerability.<br />
<br />
When a device removal is triggered (via hot-unplug or module unload),<br />
race condition can occur.<br />
<br />
The fix adds tasklet_kill() before freeing the asd_ha structure,<br />
ensuring all scheduled tasklets complete before cleanup proceeds.
