Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a request pointer being changed to point to a lock entry that has just been added to the inode list when usi...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: btrfs: fixed a race condition between direct IO writes and fsync operations when using the same file descriptor. If we have two threads that use the same file descriptor, and one of them performs direct IO writes while the other...

CVE-2023-52737

CVE-2023-52737: In the Linux kernel, when using Btrfs, fiemap could deadlock with an in-flight fsync due to not taking the inode lock (i_mutex) before fiemap operations. The root cause is that fiemap_fill_next_extent() could fault while accessing user space buffers, which creates a lock-order cyc...

kernel: denial of service in in xfs_setattr_nonsize in fs/xfs/xfs_iops.c

A flaw was found in the XFS file system in the Linux kernel. An acquired ILOCK was not freed/unlock when the call to xfsqmvopchownreserve fails and the lock is still held and can lead to denial to access for that device. This is primarily a local denial of service but could result in a remote...

UBUNTU-CVE-2019-15538

An issue was discovered in xfssetattrnonsize in fs/xfs/xfsiops.c in the Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on account of being out of disk quota. xfssetattrnonsize is failing to unlock the ILOCK after the xfsqmvopchownreserve call fails. This is primarily a local...
