CVE-2022-49833

The CVE-2022-49833 issue affects the Linux kernel's btrfs zoned handling: when cloning a btrfs_device, the associated btrfs_zoned_device_info is not cloned for zoned filesystems, which can lead to a NULL pointer dereference when accessing the device’s zone_info (e.g., when activating a zone). The...

CVE-2022-49831 btrfs: zoned: initialize device's zone info for seeding

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 btrfszoneddeviceinfo structure, otherwise mounting the filesystem will cause ...

CVE-2022-49831

The CVE relates to the Linux kernel btrfs zoned feature. The issue occurs during seeding on a zoned filesystem if each zoned device’s btrfs_zoned_device_info is not initialized, causing a NULL pointer dereference when mounting.
