While pskb_network_may_pull() ensures the packet data is\nlinear starting from the network header, it does not set or adjust the\ntransport header offset.\n\nDereferencing icmp6_hdr(skb) can therefore access out-of-bounds memory.\n\nFetch the icmp6hdr directly after ipv6hdr following pskb_network_may_pull(),\nand reload ipv6hdr in case pskb_may_pull() reallocated skb->head.\nAlso remove the unused bond argument from alb_determine_nd().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/27314f96d29b54e815e7a9b84c3273f1895e68e2","https://git.kernel.org/stable/c/3b178894931a268c09126a5b53630f343e10e296","https://git.kernel.org/stable/c/70f3995830d3f1e79faa14eb0605914f778feca9","https://git.kernel.org/stable/c/7adb1bf25b0c5cedfb49b6e82844394d4f3c0d99","https://git.kernel.org/stable/c/862c8eb6947689c44fe11353755576a3672563a5"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-98089","score":0.00173,"percentile":0.06622,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
