CVE-2026-97552 xfs: initialise error in xfs_defer_finish_one()

In the Linux kernel, the following vulnerability has been resolved: xfs: initialise error in xfsdeferfinishone xfsdeferfinishone declares error without an initialiser and only assigns it inside the loop over dfp-dfpwork. When that list is empty the loop body never runs, control falls through to t...

CVE-2026-97551

In the Linux kernel, the following vulnerability has been resolved: xfs: initialise args-total for parent pointer updates xfsparentdaargsinit builds an xfsdaargs from a zeroed xfsparentargs kmemcachezalloc, leaving args-total == 0. xfsdagrowinodeint treats that field as a running block reservatio...

CVE-2026-97550

The Linux kernel contains a logic error in the xfs filesystem regarding per_binval computation. The vulnerability stems from performing unit conversions in the wrong direction: the second parameter of xfs_buf_inval_log_space is expected in bytes , while max_binval is measured in fsblocks . This r...

CVE-2026-97548

The Linux kernel contains a vulnerability within the xfs filesystem regarding the rtrmap and rtrefcount versions of the _maxlevels_ondisk functions. These functions are responsible for computing the size of in-memory btree cursors; however, they fail to account for the inode root . This oversight...

CVE-2026-97549

The Linux kernel XFS filesystem experienced an issue where the system would under-reserve blocks during the repair of shortform (sf) directories . The root cause was an incorrect assignment of the args->total value in xrep_dir_swap_prep, which failed to account for the correct ratio between di...
