CVE-2009-0748

Linux kernel <2.6.27.19-2.6.28.7 - DoS

Title source: llm
STIX 2.1

Description

The ext4_fill_super function in fs/ext4/super.c in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 does not validate the superblock configuration, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) by attempting to mount a crafted ext4 filesystem.
