CVE-2013-6383: Linux Kernel

Medium severity, CVSS 6.9. EPSS: 0.5% chance of exploitation in the next 30 days.

The aac_compat_ioctl function in drivers/scsi/aacraid/linit.c in the Linux kernel before 3.11.8 does not require the CAP_SYS_RAWIO capability, which allows local users to bypass intended access restrictions via a crafted ioctl call.

Affected products

• Linux Linux Kernel: from 2.6.12, before 3.2.53 (fixed in 3.2.53); from 3.3, before 3.4.69 (fixed in 3.4.69); from 3.5, before 3.10.19 (fixed in 3.10.19); from 3.11, before 3.11.8 (fixed in 3.11.8)
