CVE-2026-46057

In the Linux kernel, the following vulnerability has been resolved: landlock: Fix LOG_SUBDOMAINS_OFF inheritance across fork() hook_cred_transfer() only copies the Landlock security blob when the source credential has a domain. This is inconsistent with landlock_restrict_self() which can set LOG_SUBDOMAINS_OFF on a credential without creating a domain (via the ruleset_fd=-1 path): the field is committed but not preserved across fork() because the child's prepare_creds() calls hook_cred_transf
