CVE-2026-98977 namespace: handle mount locking for automounts correctly

In the Linux kernel, the following vulnerability has been resolved: namespace: handle mount locking for automounts correctly If mounts are propagated across user namespaces, attachrecursivemnt locks every copy of the source mount to protect overmounts from vanishing and revealing the underlying...

CVE-2026-98977

The Linux kernel contains a vulnerability where attach_recursive_mnt() incorrectly handles mount locking for automounts when propagated across user namespaces . Because the kernel may use the caller's mount namespace to determine the user namespace, automounts accessed during path lookup can resu...

CVE-2026-98976

The Linux kernel contains a vulnerability where attach_recursive_mnt() incorrectly transfers the MNT_LOCKED property from a top mount to a mount moved beneath it using MOVE_MOUNT_BENEATH. This flaw allows a user namespace owner to replace a locked /proc or its root by exploiting how propagated co...

In the Linux kernel, the following vulnerability has been resolved: xfs: stop exchanging reflink flags when exchanging mappings When an exchange covers both files from offset 0 to idisksize, xmicanexchangereflinkflags assumes every mapping moved and hands the reflink flag over to the other file...

CVE-2026-98975

The Linux kernel contains a vulnerability in the XFS filesystem where the xmi_can_exchange_reflink_flags() function incorrectly assumes all mappings are moved during an exchange from offset 0 to i_disk_size. This incorrect assumption leads to the clearing of a reflink flag on files that still own...

CVE-2026-98974

The Linux kernel contains a vulnerability in the XFS filesystem involving the XFS_IOC_EXCHANGE_RANGE operation's TO_EOF flag. The root cause is that the code incorrectly swaps ondisk and incore file sizes when a nonzero offset is used, leading to incorrect file size reporting. This discrepancy ca...
