Linux kernel eCryptfs d_delete NULL pointer dereference
The Linux kernel’s eCryptfs implementation contains a NULL pointer dereference in the d_delete function (fs/ecryptfs/inode.c) in Linux kernel 2.6.31. Local attackers can trigger creation/handling of a “negative dentry” in an eCryptfs mount, leading to a NULL pointer dereference and kernel OOPS. The issue is demonstrated via operations involving a Mutt temporary directory located on an eCryptfs mount; exploitation vectors are otherwise unspecified in the provided content. The primary impact is denial of service, with a possibility of arbitrary code execution in kernel context noted by the source description.
