CVE-2009-2908: Linux Kernel

Medium severity, CVSS 4.9. EPSS: 1.2% chance of exploitation in the next 30 days.

The d_delete function in fs/ecryptfs/inode.c in eCryptfs in the Linux kernel 2.6.31 allows local users to cause a denial of service (kernel OOPS) and possibly execute arbitrary code via unspecified vectors that cause a "negative dentry" and trigger a NULL pointer dereference, as demonstrated via a Mutt temporary directory in an eCryptfs mount.

Affected products

• Linux Linux Kernel: version 2.6.31 only
