CVE-2015-8324 (CCN-108303)

Assigned:2015-11-23
Published:2015-11-23
Updated:2023-02-13
Summary:The ext4 implementation in the Linux kernel before 2.6.34 does not properly track the initialization of certain data structures, which allows physically proximate attackers to cause a denial of service (NULL pointer dereference and panic) via a crafted USB device, related to the ext4_fill_super function.
