CVE-2023-53306

CVE-2023-53306 involves the Linux kernel fsdax path used by XFS for CoW on non-shared extents. The issue arises when a previous non-shared extent is mwrited and its dax entry is left dirty, which produced a WARN at dax_insert_entry. The connected documents consistently describe this as a resolved...

CVE-2023-53306 fsdax: force clear dirty mark if CoW

In the Linux kernel, the following vulnerability has been resolved: fsdax: force clear dirty mark if CoW XFS allows CoW on non-shared extents to combat fragmentation1. The old non-shared extent could be mwrited before, its dax entry is marked dirty. This results in a WARNing: 28.512349 ----------...

CVE-2022-50293

CVE-2022-50293 affects the Linux kernel btrfs subsystem. When dropping file extent items for a range, ENOMEM could trigger a BUG_ON() path in btrfs_drop_extents(); the fix replaces those BUG_ON()s with proper transaction abort and error return handling. This means that instead of halting the tran...
