This could lead to out-of-bounds access if the\nmulti-link element or its corresponding fragment elements are the last\nelements in the IEs buffer.\n\nTo address this issue, correctly calculate the remaining IEs length by\ndeducting the multi-link element end offset from total IEs end offset.\n\n## Affected\n\n- `linux_kernel >= 6.5, < 6.6.91`\n- `linux_kernel >= 6.7, < 6.12.29`\n- `linux_kernel >= 6.13, < 6.14.7`\n- `linux_kernel = 6.15`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.14.7`","depth":"twilight","depthScore":45,"depthScoreParts":{"impact":44.6,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
