PUBLISHED

Description

The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.15.15 does not always initialize the crc32c checksum driver, which allows attackers to cause a denial of service (ext4_xattr_inode_hash NULL pointer dereference and system crash) via a crafted ext4 image.

Vendor	Product	Versions
n/a	Linux kernel through version 4.15	affected `Linux kernel through version 4.15`
