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...

EUVD-2026-59677

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...

In the Linux kernel, the following vulnerability has been resolved: binfmtmisc: don't leak the user namespace when the mount fails bmgettree takes a reference to the user namespace and hands it to gettreekeyed as the sget key. sgetfc moves that reference into sb-sfsinfo and clears fc-sfsinfo, so...

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...
