CVE-2013-6763: Linux Kernel

Medium severity, CVSS 6.9. EPSS: 0.6% chance of exploitation in the next 30 days.

The uio_mmap_physical function in drivers/uio/uio.c in the Linux kernel before 3.12 does not validate the size of a memory block, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via crafted mmap operations, a different vulnerability than CVE-2013-4511.

Affected products

• Linux Linux Kernel: before 3.2.53 (fixed in 3.2.53); from 3.3, before 3.4.71 (fixed in 3.4.71); from 3.5, before 3.10.19 (fixed in 3.10.19); from 3.11, before 3.11.8 (fixed in 3.11.8)
