CVE-2022-50090
CVE-2022-50090 relates to the Linux kernel/Btrfs: it replaces the hard-coded limit BTRFS_MAX_EXTENT_SIZE with fs_info->max_extent_size. On zoned filesystems, data writes are limited by max_zone_append_size, and a large ordered extent can trigger more extents than expected, causing the estimato...

CVE-2022-50089
CVE-2022-50089 affects the Linux kernel with the btrfs file system. The issue occurs when cow_file_range() fails mid-allocation (unlock=0) and may leave pages locked, potentially causing a hung task in zoned btrfs setups (as described in the provided reports). The included details show that the f...

CVE-2022-50067
Concretely, CVE-2022-50067 affects Linux kernel’s btrfs relocation logic: if prepare_to_relocate() triggers a failure during a transaction, the code frees the relocation control (rc) but does not clear fs_info->reloc_ctl, leading to a use-after-free when btrfs_init_reloc_root() later reads rc....
