CVE-2026-31577

CVE-2026-31577 affects the Linux kernel nilfs2 filesystem. The vulnerability is a NULL i_assoc_inode dereference in nilfs_mdt_save_to_shadow_map during GC if NILFS_IOCTL_CLEAN_SEGMENTS is invoked immediately after mount, before any btree operation on the DAT inode. The root cause is i_assoc_inode...

SUSE CVE-2026-31448

In the Linux kernel, the following vulnerability has been resolved: ext4: avoid infinite loops caused by residual data On the mkdir/mknod path, when mapping logical blocks to physical blocks, if inserting a new extent into the extent tree fails in this example, because the file system disabled th...

SUSE CVE-2026-31455

In the Linux kernel, the following vulnerability has been resolved: xfs: stop reclaim before pushing AIL during unmount The unmount sequence in xfsunmountflushinodes pushed the AIL while background reclaim and inodegc are still running. This is broken independently of any use-after-free issues -...

SUSE CVE-2026-31463

In the Linux kernel, the following vulnerability has been resolved: iomap: fix invalid folio access when iblkbits differs from I/O granularity Commit aa35dd5cbc06 "iomap: fix invalid folio access after folioendread" partially addressed invalid folio access for folios without an ifs attached, but ...

CVE-2026-31463

A flaw was found in the Linux kernel's iomap subsystem. This vulnerability occurs when the block size of an inode iblkbits differs from the granularity used for input/output I/O operations. This mismatch can lead to invalid access of data pages folios during read operations, potentially causing...

CVE-2026-31455

A flaw was found in the Linux kernel's XFS file system. During the unmount process, the system attempts to flush data while background cleanup and inode garbage collection inodegc operations are still active. This improper synchronization can lead to data integrity issues or system instability, a...
