In the Linux kernel, the following vulnerability has been resolved: binfmt_misc: don't warn when the mount is completed from another user namespace… (CVE-2026-74618)CVE-2026-74618 0 A vulnerability in the Linux kernel's binfmt_misc subsystem caused WARN_ON() kernel warnings when completing a mount from another user namespace. This occurs because fsopen() records the caller's user namespace but fsconfig() does not verify that the task issuing FSCONFIG_CMD_CREATE matches the creator's namespace. An unprivileged user can trigger repeated WARN_ON() warnings, potentially tainting the kernel and flooding logs, and causing a kernel panic if panic_on_warn is enabled. The issue has been resolved by refusing the mount and stopping the warnings, as the namespaces do not need to match for correct operation.
