Linux Distros Unpatched Vulnerability : CVE-2026-78409

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to opentree with ATSYMLINKNOFOLLOW. That...

EUVD-2026-70107

The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to opentree with ATSYMLINKNOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with...

CVE-2026-78410 Util-linux: util-linux: restricted bind mounts do not pin the source, allowing x-mount.owner/group/mode redirection

A flaw was found in util-linux. Restricted bind mounts take the source path from fstab but do not pin that source before the privileged mount. A local unprivileged user who can replace the authorized source or a writable ancestor can redirect SUID mount8 to bind another host directory. If the fst...

CVE-2026-78422 zbus_polkit: polkit authorization bypass via PID reuse due to incorrect D-Bus type for the subject UID

Subject::newforowner in the zbuspolkit crate encodes the uid entry of a unix-process polkit subject as an unsigned 32-bit integer D-Bus type u, whereas the org.freedesktop.PolicyKit1.Authority interface specifies a signed 32-bit integer D-Bus type i. Because of this type mismatch, polkit silently...

EUVD-2026-66234

When a process calls execve2 to execute a setuid or setgid image, hwpmc4 is supposed to detach PMCs owned by unprivileged processes. An inverted check meant that this scenario was not handled properly. An unprivileged local user who has attached PMCs to a process can continue monitoring it after...

CVE-2026-74716

A flaw was found in the Linux kernel's amdxdna graphics driver. An unprivileged local user could exploit a vulnerability in how the driver handles memory management operations. By performing specific memory mapping and access patterns, a user could trigger an assertion failure, leading to a syste...

CVE-2026-74618

A flaw was found in the Linux kernel's binfmtmisc component. An unprivileged local user can exploit this vulnerability by manipulating user and mount namespaces to repeatedly trigger a warning condition during the mounting of binfmtmisc. This repeated triggering can lead to kernel log flooding,...

CVE-2026-74619

A flaw was found in the Linux kernel's overlay filesystem overlayfs. An unprivileged local user can repeatedly trigger a warning condition by manipulating user and mount namespaces and file system context operations. This can lead to kernel log flooding, kernel tainting, and potentially a system...
