UBUNTU-CVE-2024-46733

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix qgroup reserve leaks in cowfilerange In the buffered write path, the dirty page owns the qgroup reserve until it creates an orderedextent. Therefore, any errors that occur before the orderedextent is created must free...

CVE-2024-46752

CVE-2024-46752 - Mode C (detailed, verified): The vulnerability is in the Linux kernel’s btrfs code path; specifically, update_ref_for_cow() previously used BUG_ON() and now returns an error, logs an error, and aborts the transaction when an extent buffer in the relocation tree lacks the full bac...

CVE-2024-46751

CVE-2024-46751 affects the Linux kernel btrfs path where a 0 reference count could trigger a BUG_ON() in btrfs_lookup_extent_info(). The vulnerability arises from the incorrect BUG_ON() and is fixed by changing the code to return -EUCLEAN, abort the transaction, and log an error instead. This red...
