CVE-2019-10140 Detail

Modified

This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.

Description

A vulnerability was found in Linux kernel's, versions up to 3.10, implementation of overlayfs. An attacker with local access can create a denial of service situation via NULL pointer dereference in ovl_posix_acl_create function in fs/overlayfs/dir.c. This can allow attackers with ability to create directories on overlayfs to crash the kernel creating a denial of service (DOS).
