SUSE CVE-2025-71309

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: fix deadlock in nireadfoliocmpr Syzbot reported a task hung in nireadpagecmpr now nireadfoliocmpr. This is caused by a lock inversion deadlock involving the inode mutex nilock and page locks. Scenario: 1. Task A enters...

SUSE CVE-2026-45915

In the Linux kernel, the following vulnerability has been resolved: fat: avoid parent link count underflow in rmdir Corrupted FAT images can leave a directory inode with an incorrect inlink e.g. 2 even though subdirectories exist. rmdir then unconditionally calls dropnlinkdir and can drive inlink...

SUSE CVE-2026-46002

In the Linux kernel, the following vulnerability has been resolved: ext2: reject inodes with zero inlink and valid mode in ext2iget ext2iget already rejects inodes with inlink == 0 when imode is zero or idtime is set, treating them as deleted. However, the case of inlink == 0 with a non-zero mode...

CVE-2026-45924

A flaw was found in ksmbd, a component of the Linux kernel. This vulnerability occurs because ksmbdvfskernpathendremoving is not called on certain error paths, leading to unbalanced inode locks and references. This can result in potential deadlocks and unbalanced locks, which may cause system...

CVE-2026-46040

A flaw was found in the Linux kernel's inotify subsystem. When the fsnotifyaddinodemarklocked function fails during the creation of a new watch, the system does not properly decrement the watch count. This oversight can lead to a watch count leak, where repeated failures exhaust the maximum user...

CVE-2026-46046

A flaw was found in the Linux kernel's ext4 filesystem. A reference count refcount leak occurs in the ext4xattrinodedecrefall function. This issue arises because the iloc.bh buffer head, acquired by ext4getinodeloc, is not properly released with brelse. This can lead to resource exhaustion or...
