CVE-2022-49849

CVE-2022-49849 fixes a Linux kernel flaw in the Btrfs dev_args_match_device path. When devid is set to (u64)-1 via ioctl, the match of devid may be skipped and device matching may succeed incorrectly. The issue was introduced by a patch that added the function used to match devices; the two match...

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

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. Multiple sources confirm this vulnerability and its resolution in the...
