CVE-2018-1092: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 1.9% chance of exploitation in the next 30 days.

The ext4_iget function in fs/ext4/inode.c in the Linux kernel through 4.15.15 mishandles the case of a root directory with a zero i_links_count, which allows attackers to cause a denial of service (ext4_process_freed_data NULL pointer dereference and OOPS) via a crafted ext4 image.

Affected products

• Linux Linux Kernel: up to and including 4.15.15
