CVE-2013-2015: Linux Kernel

Medium severity, CVSS 4.7. EPSS: 0.4% chance of exploitation in the next 30 days.

The ext4_orphan_del function in fs/ext4/namei.c in the Linux kernel before 3.7.3 does not properly handle orphan-list entries for non-journal filesystems, which allows physically proximate attackers to cause a denial of service (system hang) via a crafted filesystem on removable media, as demonstrated by the e2fsprogs tests/f_orphan_extents_inode/image.gz test.

Affected products

• Linux Linux Kernel: up to and including 3.7.2; version 3.0 only; version 3.0.1 only; version 3.0.2 only; version 3.0.3 only; version 3.0.4 only; …
