Doc Text:
A flaw was found in the Linux kernel qla2xxx SCSI driver. A static analysis tool reported that the array vha->host_str, sized to hold 16 characters, could be indexed with values outside its valid range, potentially leading to out-of-bounds writes. The root cause was the use of sprintf() without enforcing proper bounds checks. An unprivileged local user with access to trigger the affected driver logic may be able to cause a kernel crash or hang, resulting in a denial of service.
