Vulnerability from cvelistv5 – Published: 2016-05-02 10:00 – Updated: 2024-08-06 08:13
VLAI
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.
