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,...

In the Linux kernel, the following vulnerability has been resolved: binfmtmisc: don't warn when the mount is completed from another user namespace fsopen records the caller's user namespace in fc-userns and hands back an ordinary file descriptor. Nothing ties the task that calls...

CVE-2026-74618

CVE-2026-74618 affects the Linux kernel 's binfmt_misc filesystem. The root cause is a WARN_ON() in bm_fill_super() that triggers when a binfmt_misc mount is completed from a different user namespace than the one that created the fscontext via fsopen(). Because fsconfig(FSCONFIG_CMD_CREATE) autho...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - binfmtmisc: don't warn when the mount is completed from another user namespace fsopen records the caller's user namespace in fc-userns and hands back an ordinar...

CVE-2026-74487

A flaw was found in the binfmtmisc component of the Linux kernel. When a binfmtmisc entry is registered with the MISCFMTOPENFILE flag, it opens an interpreter file and denies write access. Upon removal of this entry, the write access is not properly restored. This oversight can lead to a persiste...

CVE-2026-74484

A flaw was found in the Linux kernel's binfmtmisc component. A local attacker can exploit this vulnerability by registering an 'F' entry that points to its own instance or uses it as an overlayfs lower layer. This self-pinning prevents the associated file from being closed, leading to a resource...

CVE-2026-74483

A flaw was found in the binfmtmisc component of the Linux kernel. An unprivileged local attacker, operating under specific memory constraints a tight memory cgroup, could repeatedly trigger a failure in the bmfillsuper function during a mount operation. This failure prevents the proper release of...

CVE-2026-74485

A flaw was found in the binfmtmisc component of the Linux kernel. An unprivileged local user, operating within a user namespace, could exploit this vulnerability. By registering a binfmtmisc string where the chosen delimiter character is also a flag character, the system's flag field parser can...

CVE-2026-74486

A flaw was found in the Linux kernel's binfmtmisc component. This vulnerability arises from an inconsistency in how write access is managed for cloned interpreter files. When a pre-content watch is applied to an interpreter after its registration, subsequent executions through that entry can lead...

SUSE CVE-2026-74484

In the Linux kernel, the following vulnerability has been resolved: binfmtmisc: don't let an 'F' entry pin its own instance An entry registered with 'F' opens its interpreter at registration time and holds that file until the entry is freed. Any entry nobody removes by hand only gets closed once...
