CVE-2011-1748: Linux Kernel

Medium severity, CVSS 4.9. EPSS: 0.4% chance of exploitation in the next 30 days.

The raw_release function in net/can/raw.c in the Linux kernel before 2.6.39-rc6 does not properly validate a socket data structure, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted release operation.

Affected products

• Linux Linux Kernel: before 2.6.39 (fixed in 2.6.39); version 2.6.39 only
