Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-11-10 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

btrfs: zoned: initialize device's zone info for seeding

When performing seeding on a zoned filesystem it is necessary to initialize each zoned device's btrfs_zoned_device_info structure, otherwise mounting the filesystem will cause a NULL pointer dereference.

This was uncovered by fstests' testcase btrfs/163.

Severity ?

5.5 (Medium)
