Description

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.
