So we need to check the rphy to avoid possible NULL pointer access.\n\nIf sas_rphy_add() returned with failure, rphy is set to NULL. We would\naccess the rphy in the following lines which would also result NULL pointer\naccess.\n\n## Affected\n\n- `Linux >= d60000cb1195a464080b0efb4949daf7594e0020 < 090305c36185c0547e4441d4c08f1cf096b32134`\n- `Linux >= ce1a69cc85006b494353911b35171da195d79e25 < 6f0c2f70d9929208d8427ec72c3ed91e2251e289`\n- `Linux >= 6a92129c8f999ff5b122c100ce7f625eb3e98c4b < 9937f784a608944107dcc2ba9a9c3333f8330b9e`\n- `Linux >= d17bca3ddfe507874cb826d32721552da12e741f < b5e5bbb3fa5f8412e96c5eda7f4a4af6241d6bd3`\n- `Linux >= 78316e9dfc24906dd474630928ed1d3c562b568e < a26c775ccc4cfe46f9b718b51bd24313053c7e0b`\n- `Linux >= 78316e9dfc24906dd474630928ed1d3c562b568e < d3c57724f1569311e4b81e98fad0931028b9bdcd`\n- `Linux 6f6768e2fc8638fabdd8802c2ef693d7aef01db1`\n- `Linux >= 5.4.229 < 5.4.238`\n- `Linux >= 5.10.163 < 5.10.176`\n- `Linux >= 5.15.86 < 5.15.104`\n- `Linux >= 6.1.2 < 6.1.21`\n- `Linux >= 6.0.16 < 6.1`\n- `Linux 6.2`\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":[]}
