EUVD-2026-86859

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...

In the Linux kernel, the following vulnerability has been resolved: xfs: fix the rtrmap and rtrefcount maxlevelsondisk functions The maxlevelsondisk functions are used to compute the size of in-memory btree cursors for each btree type. Unfortunately, LOLLM noticed that the rtrmap and rtrefcount...

CVE-2026-97548 xfs: fix the rtrmap and rtrefcount _maxlevels_ondisk functions

In the Linux kernel, the following vulnerability has been resolved: xfs: fix the rtrmap and rtrefcount maxlevelsondisk functions The maxlevelsondisk functions are used to compute the size of in-memory btree cursors for each btree type. Unfortunately, LOLLM noticed that the rtrmap and rtrefcount...

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...

EUVD-2026-86854

In the Linux kernel, the following vulnerability has been resolved: xfs: don't spin forever on zero-length dirents when salvaging them LOLLM noticed that xrepdirrecoverdata can spin forever if it encounters an unused dirent that claims to have length zero. Fix that, and prevent the same thing fro...

CVE-2026-97547 xfs: fix exchange-range reflink flag clearing issue with INO1_WRITTEN

In the Linux kernel, the following vulnerability has been resolved: xfs: fix exchange-range reflink flag clearing issue with INO1WRITTEN When exchanging two full-file ranges, xmicanexchangereflinkflags can move the reflink inode flag from the file that currently has it to the other file, as long ...

CVE-2026-97547

The Linux kernel contains a vulnerability in the XFS filesystem related to xmi_can_exchange_reflink_flags(). When exchanging two full-file ranges with the XFS_EXCHMAPS_INO1_WRITTEN flag set, the system may incorrectly move the reflink inode flag . This occurs because the operation can skip hole a...

CVE-2026-97546 xfs: don't spin forever on zero-length dirents when salvaging them

In the Linux kernel, the following vulnerability has been resolved: xfs: don't spin forever on zero-length dirents when salvaging them LOLLM noticed that xrepdirrecoverdata can spin forever if it encounters an unused dirent that claims to have length zero. Fix that, and prevent the same thing fro...

CVE-2026-97546

The Linux kernel contains a vulnerability in the xfs filesystem where the function xrep_dir_recover_data can enter an infinite loop (spin forever ). This occurs when the system encounters an unused directory entry (dirent ) that claims to have a length of zero during the salvaging process. The pr...

CVE-2026-97545

The Linux kernel contains a vulnerability in the xfs filesystem where xfs_btree_bload_prep_block fails to release new_bp if xfs_btree_bload_drop_buf encounters an IO error during the writing of the delwri buffer list to disk. This flaw results in a lost locked buffer . Remediation is provided via...
