EUVD-2026-103691

In the Linux kernel, the following vulnerability has been resolved: smb: client: use finishnoopen for non-regular inodes An OCREAT open can find an existing symlink or another non-regular inode. cifsatomicopen calls finishopen on it and attaches a cifsFileInfo. Symlink inodes have no CIFS release...

CVE-2026-98450

The Linux kernel contains a vulnerability in the SMB client where the compound_send_recv() function fails to properly manage remote handles during compound wait errors. If a later wait is interrupted or a later MID fails during synchronization, an earlier CREATE operation might already have opene...

CVE-2026-98450 smb: client: close completed creates on compound wait errors

In the Linux kernel, the following vulnerability has been resolved: smb: client: close completed creates on compound wait errors compoundsendrecv waits for responses in order. If a later wait is interrupted, or if a later MID fails during response synchronization, an earlier CREATE may already ha...

CVE-2026-98449

The Linux kernel contains a vulnerability in the SMB client where compound requests fail to properly manage mids during a reconnect. Specifically, compound_send_recv() unlocks the server without removing mids from the pending_mid_q after a send failure. During reconnection, cifs_abort_connection(...

CVE-2026-98449 smb: client: delete compound mids on send failure before unlock

In the Linux kernel, the following vulnerability has been resolved: smb: client: delete compound mids on send failure before unlock When sending a compound request fails, smbsendrqst kicks off a reconnect. compoundsendrecv still has those mids on pendingmidq, but it unlocks the server without...

CVE-2026-98448

The Linux kernel contains a vulnerability within the xfs filesystem component where the system fails to release an igrab'd reference to an orphanage directory inode if a chown operation fails. This flaw results in a reference leak. Remediation is available through kernel updates, as evidenced by ...

CVE-2026-98448 xfs: release orphanage dir inode if chown fails

In the Linux kernel, the following vulnerability has been resolved: xfs: release orphanage dir inode if chown fails LOLLM points out that we leak the igrab'd reference to the orphanage directory inode if chowning it fails. Fix that...

CVE-2026-98447

The Linux kernel contains a vulnerability in the xfs filesystem where the inode btree root formatting methods perform a wild memcpy access . The root cause is that these methods copy too many bytes because there is only one set of keys in node blocks instead of two, leading to memory corruption o...

CVE-2026-98447 xfs: fix wild memcpy access when formatting ondisk rtrefcount btree roots

In the Linux kernel, the following vulnerability has been resolved: xfs: fix wild memcpy access when formatting ondisk rtrefcount btree roots LOLLM noticed that the inode btree root formatting methods copy too many bytes -- there's only one set of keys in node blocks, not two. This causes memory...

CVE-2026-98446

The Linux kernel contains a vulnerability in the xfs filesystem. Specifically, within xfs_metafile_resv_init , if the reservable fdblocks for a metadata btree file falls below the space already used by that file, a hidden_space subtraction can underflow . This underflow causes xfs_dec_fdblocks to...

CVE-2026-98446 xfs: don't let hidden_space go negative in xfs_metafile_resv_init

In the Linux kernel, the following vulnerability has been resolved: xfs: don't let hiddenspace go negative in xfsmetafileresvinit LOLLM points out that if the amount of fdblocks that we can reserve for a metadata btree file goes below the space already used by that file, then the hiddenspace...

CVE-2026-98445 xfs: don't let memory failures leak blocks and kill repairs

In the Linux kernel, the following vulnerability has been resolved: xfs: don't let memory failures leak blocks and kill repairs LOLLM complains that a memory allocation failure in xrepnewbtaddblocks results in online repair leaking blocks that were previously allocated to write a new btree, but t...

CVE-2026-98445

The Linux kernel XFS filesystem contains a vulnerability where a memory allocation failure in xrep_newbt_add_blocks causes online repairs to leak blocks previously allocated for a new btree. Due to codebase limitations, callers cannot undo the transaction and return an error, which could otherwis...
