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-2026-74484

CVE-2026-74484 concerns the Linux kernel’s binfmt_misc feature: an entry registered with the character 'F' can cause the interpreter to pin itself, preventing proper unregistration and leading to a DoS with leaked resources (including user namespaces). The issue arises when the interpreter’s file...

CVE-2026-74483

CVE-2026-74483 affects the Linux kernel: binfmt_misc may leak a user namespace across mounts when bm_fill_super() fails. The root cause is improper ownership transfer of the user namespace through s_fs_info leading to a leak, which is mitigated by dropping the reference in kill_sb() so the namesp...
