CVE-2022-49833

In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: clone zoned device info when cloning a device When cloning a btrfsdevice, we're not cloning the associated btrfszoneddeviceinfo structure of the device in case of a zoned filesystem. Later on this leads to a NULL...

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...
