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. The Linux kernel CVE team has assigned CVE-2025-71075 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/scsi/aic94xx/aic94xx_init.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/b3e655e52b98a1d3df41c8e42035711e083099f8 https://git.kernel.org/stable/c/e354793a7ab9bb0934ea699a9d57bcd1b48fc27b https://git.kernel.org/stable/c/a41dc180b6e1229ae49ca290ae14d82101c148c3 https://git.kernel.org/stable/c/751c19635c2bfaaf2836a533caa3663633066dcf https://git.kernel.org/stable/c/f6ab594672d4cba08540919a4e6be2e202b60007
