  "details": "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_transfer() which skips the copy when domain is NULL.  This breaks the documented use case where a process mutes subdomain logs before forking sandboxed children: the children lose the muting and their domains produce unexpected audit records.  Fix this by unconditionally copying the Landlock credential blob.",
