Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the ocfs2 file system’s ocfs2groupextend function. This function assumes that the global bitmap f...

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...

EUVD-2026-24794

This is broken independently of any use-after-free issues -...

EUVD-2026-24790

In the Linux kernel, the following vulnerability has been resolved: ext4: replace BUGON with proper error handling in ext4readinlinefolio Replace BUGON with proper error handling when inline data size exceeds PAGESIZE. This prevents kernel panic and allows the system to continue running while...

EUVD-2026-24788

In the Linux kernel, the following vulnerability has been resolved: ext4: publish jinode after initialization ext4inodeattachjinode publishes ei-jinode to concurrent users. It used to set ei-jinode before jbd2journalinitjbdinode, allowing a reader to observe a non-NULL jinode with ivfsinode still...

CVE-2026-31455

CVE-2026-31455 pertains to the Linux kernel, specific to the XFS unmount path. During unmount, in xfs_unmount_flush_inodes(), the AIL is pushed while background reclaim and inodegc may still be running, which can lead to inodes being dirtied or re-queued into the AIL. The provided fix reorders th...
