Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: “fs/ntfs3: Replace inodetrylock with inodelock” This change is reflected in commit 69505fe98f198ee813898cbcaf6770949636430b. Initially, the conditional lock acquisition was removed to fix a bug in xfstest that was observed during...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: gfs2: Fix for fiemap page faults In gfs2fiemap, we call iomapfiemap while holding the inode lock. This can lead to recursive locking if the fiemap buffer is memory-mapped to the same inode, and accessing it triggers a page...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: btrfs: Lock the inode in shared mode before starting fiemap. Currently, fiemap does not lock the inode itself VFS lock; instead, it only locks a file range within the inode’s io tree. However, this can lead to a deadlock if there...

SUSE CVE-2026-80535

In the Linux kernel, the following vulnerability has been resolved: xfs: don't double-lock when deleting a self-referential directory LOLLM notices that the dirtree scrubber can detect a directory that refers to itself. In this case, it's not correct for the directory tree repair code to try to...

CVE-2026-74343

In the Linux kernel, the following vulnerability has been resolved: kernfs: fix xattr race condition with multiple superblocks Multiple superblocks with different namespaces can share the same kernfsnode when kernfstestsuper finds a matching root but different namespace. This means multiple inode...

CVE-2026-72190

CVE-2026-72190 : The Linux kernel NTFS handling has a deadlock in rename due to mismatched lock ordering on mrec_lock between inodes and their parent directories. The functions ntfs_file_fsync(), ntfs_dir_fsync(), and __ntfs_write_inode() acquire an inode’s mrec_lock before its parent directory’s...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: In the vfs module, a race condition occurred regarding the mFlags field. ksmbd maintains states such as “delete-on-close” and “pending-delete” in the mFlags field of the ksmbdinode structure. In the vfscache.c code, thi...

CVE-2025-68185

In the Linux kernel, the following vulnerability has been resolved: nfs4setupreaddir: insufficient locking for -dparent-dinode dereferencing Theoretically it's an oopsable race, but I don't believe one can manage to hit it on real hardware; might become doable on a KVM, but it still won't be easy...

UBUNTU-CVE-2023-53838

DEBIAN-CVE-2025-39734

In the Linux kernel, the following vulnerability has been resolved: Revert "fs/ntfs3: Replace inodetrylock with inodelock" This reverts commit 69505fe98f198ee813898cbcaf6770949636430b. Initially, conditional lock acquisition was removed to fix an xfstest bug that was observed during internal...

CVE-2025-39734

CVE-2025-39734 affects the Linux kernel component fs/ntfs3 in the NTFS file-system path. The issue stems from a revert of the inode_trylock versus inode_lock handling (commit 69505fe98f198ee813898cbcaf6770949636430b). The description notes that previously conditional lock acquisition was removed ...
