This\nallows the operation to proceed for non-TDLS stations, causing\nunintended side effects like modifying channel context and HT\nprotection before failing.\n\nAdd a check for sta->sta.tdls early in the ENABLE_LINK case, before\nany side effects occur, to ensure the operation is only allowed for\nactual TDLS peers.\n\n## Affected\n\n- `linux_kernel >= 3.2, < 6.12.81`\n- `linux_kernel >= 6.13, < 6.18.22`\n- `linux_kernel >= 6.19, < 6.19.12`\n- `linux_kernel = 7.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.19.12`","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":39.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
