This prevents the explicitly unplugged control\ndomains from being removed the KVM guest. The bitmap_and function is used\ninstead.","published":"2026-09-16T11:17:06.320","modified":"2026-09-16T11:17:06.320","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/02e72909453dee2f8a09f78819f9a9cb902dfbdc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/12871a4269f139221c9fde9ea3eb69c9228f59d4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2ff68bf414de167bc138e6e211ee1ad3ab3c5052"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4bffadde7fc49b00493fb78c6376f958998d4b8c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6b8a02e216f6b520cc029e43ddc83956605135d5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f7d66afc34bc6e833c8ebe56973afec35f473bc1"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T11:17:06.320"}}
