AI-suggested

A fix is available that replaces the use of memset() with memset_io() for clearing the QLAFX00 request ring slot in the qla2xxx driver. Users should apply the updated Linux kernel version containing this fix to prevent crashes related to this issue.

Description

A vulnerability in the Linux kernel's qla2xxx SCSI driver related to improper clearing of the QLAFX00 request ring slot has been resolved. The issue involved using a plain memset() on I/O memory, which can cause invalid memory operations on certain architectures like ARM64, potentially leading to synchronous external aborts (crashes). The fix replaces memset() with memset_io() to correctly clear the device I/O memory region.
