If\nthe rhashtable insertion reports an error or an existing destination, the\nfunction discards its candidate but retains the reservation. No new path\nis installed in any of these cases.\n\nRelease the reservation whenever the candidate is not installed.\n\n## Affected\n\n- `Linux >= ae76eef027f75fadd8a8eda55ee07707f077aacb < 56691ed9ef792f180e008a43294a4dc059fbeca2`\n- `Linux >= ae76eef027f75fadd8a8eda55ee07707f077aacb < a613c891906b558c10a4fa98ca29747b98e857cb`\n- `Linux >= ae76eef027f75fadd8a8eda55ee07707f077aacb < a59eca4557c7462aad1b160011013290a92de97d`\n- `Linux >= ae76eef027f75fadd8a8eda55ee07707f077aacb < 7325a44474f20c1393a1c114c6811abce6ddfaf4`\n- `Linux 3.10`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
