If we matched a state\nfor CPU2 in the state_cache while the lookup started on CPU1, we will\njump to \"found\", but the \"best\" state that we got will be ignored and\nwe will enter the \"acquire\" block. This block uses state_ptrs, which\nisn't initialized at this point.\n\nLet's initialize state_ptrs just after taking rcu_read_lock. This will\nalso prevent a possible misuse in the future, if someone adjusts this\nfunction.\n\n## Affected\n\n- `Linux >= a16871c7832ea6435abb6e0b58289ae7dcb7e4fc < 6bf2daafc51bcb9272c0fdff2afd38217337d0d3`\n- `Linux >= e952837f3ddb0ff726d5b582aa1aad9aa38d024d < 463562f9591742be62ddde3b426a0533ed496955`\n- `Linux >= e952837f3ddb0ff726d5b582aa1aad9aa38d024d < 94d077c331730510d5611b438640a292097341f0`\n- `Linux 80610185e9dd2ef7c0a4818a47390a8655b3dc27`\n- `Linux b86dc510308d7a8955f3f47a4fea4bef887653e4`\n- `Linux dd4c2a174994238d55ab54da2545543d36f4e0d0`\n- `Linux >= 6.12.13 < 6.12.41`\n- `Linux >= 6.1.191 < 6.2`\n- `Linux >= 6.6.120 < 6.7`\n- `Linux >= 6.13.2 < 6.14`\n- `Linux 6.14`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
