## Overview

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.

## Affected

- `linux_kernel >= 2.6.19.1, < 5.10.248`
- `linux_kernel >= 5.11, < 5.15.198`
- `linux_kernel >= 5.16, < 6.1.160`
- `linux_kernel >= 6.2, < 6.6.120`
- `linux_kernel >= 6.7, < 6.12.64`
- `linux_kernel >= 6.13, < 6.18.3`
- `linux_kernel = 2.6.19`
- `linux_kernel = 6.19`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.18.3`
