CVE-2011-3363: Linux Kernel

Medium severity, CVSS 6.5. EPSS: 0.8% chance of exploitation in the next 30 days.

The setup_cifs_sb function in fs/cifs/connect.c in the Linux kernel before 2.6.39 does not properly handle DFS referrals, which allows remote CIFS servers to cause a denial of service (system crash) by placing a referral at the root of a share.

Affected products

  • Linux Linux Kernel: before 2.6.39 (fixed in 2.6.39)
  • Red Hat Enterprise Linux: version 4.0 only
