I found this double-fetch vulnerability when I was doing my research on double-fetch issue analysis, and Id like to make an announcement here. This was found in Linux kernel file Linux-4.5/drivers/scsi/aacraid/commctrl.c, and crafted user space data change under race condition will lead to over-boundary access in kernel structure or local buffer, and serious consequence might be caused. ============================================== 1. Affected Versions: Linux Kernel 4.5 and earlier versions. 2. Detailed description in my report to Kernel Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=116751 3. CVE: The Common Vulnerabilities and Exposures (CVE) project has assigned the entry CVE-2016-6480 to this issue. Even though some maintainers have confirmed this issue on the mailing list, this problem has not yet been patched since my first report three months ago. I hope this could be patched as soon as possible. Kind regards Pengfei Wang
