CVE-2026-99174

A flaw was found in the Linux kernel's ext4 file system. A local user could exploit a race condition during concurrent file path lookup and filesystem unmount operations. When resolving a symbolic link as the filesystem's last mount reference is released, the kernel may dereference a null pointer...

CVE-2026-98980

A flaw was found in the Linux kernel. A race condition during reference-based path lookup allows a local user to access files hidden beneath mount points, resulting in information disclosure. When an overmounted file or directory is unlinked or removed while another process traverses the path, th...

Astra Linux – Vulnerability in qtbase-opensource-src

In Qt 5.9.x through 5.15.x before 5.15.9, and 6.x before 6.2.4 on Linux and UNIX, QProcess could execute a binary from the current working directory when it was not found in the PATH...

Linux Kernel Security Vulnerabilities

The Linux kernel version 2.6.30 has a security vulnerability. This vulnerability arises from ocfs2’s failure to verify the count of directory index entries and block capacity when reading metadata. As a result, ocfs2dxdirsearch performs traversal operations without proper boundary checks. A...

CVE-2026-49421: Improper Check for Dropped Privileges

The kernel function that implements unlinkat2 and funlinkat2 validated the ATRESOLVEBENEATH flag but failed to pass it through to the underlying path lookup. The flag was silently dropped, so path resolution was not actually restricted. A process that uses ATRESOLVEBENEATH with unlinkat2 or...

CVE-2026-68083

CVE-2026-68083 affects ksmbd (Linux kernel in-kernel SMB server). The issue is a path-resolution bug in ksmbd_vfs_kern_path_create() where an SMB2 create/mkdir/hardlink path can leverage a ".." component to escape the share, because the rooted open lookup uses LOOKUP_BENEATH for the SMB2 path but...

CVE-2026-43895

jq is a command-line JSON processor. In 1.8.1 and earlier, jq accepts embedded NUL bytes in import paths at the jq-language level, but later resolves those paths through C string operations during module and data-file lookup. This creates a mismatch between the logical import string that policy o...
