This happens on the\nnormal registration path when the core checks the voltage constraints\nagainst every selector. TPS652G1 uses the same descriptors and is\naffected too.\n\nUse ARRAY_SIZE() so the count always matches the table.\n\n## Affected\n\n- `Linux >= 54308f24ce510a3ba1bf2e0ebc8b9c8a577b3c3b < 1ea151615a82fd94f25e38b2cc7eeac49112508b`\n- `Linux >= 00c826525fbae0230f6c3e9879e56d50267deb42 < 66b7da589b2ce44a02b8387c6160e9254685f34f`\n- `Linux >= 00c826525fbae0230f6c3e9879e56d50267deb42 < f6fbe9c6b39968a7696b9badef4bc29331a6376a`\n- `Linux >= 00c826525fbae0230f6c3e9879e56d50267deb42 < f3423b56be12208a393274afb9a5e3d67fc58ce3`\n- `Linux >= 00c826525fbae0230f6c3e9879e56d50267deb42 < 2f15518682c779b1014552cb2ccb4a2052f85f27`\n- `Linux >= 6.6.157 < 6.6.160`\n- `Linux 6.10`\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":[]}
