{"id":"CVE-2026-68310","summary":"wifi: mt76: mt7915: guard HE capability lookups","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7915: guard HE capability lookups\n\nmt7915_mcu_bss_he_tlv() and mt7915_mcu_sta_bfer_tlv() both run after\nchecking HE support, then dereference the HE PHY capability returned by\nmt76_connac_get_he_phy_cap(). That helper can return NULL when no\ncapability entry matches the vif type.\n\nFetch the capability before appending the TLV and skip the HE-specific\nsetup when no matching capability is available.","modified":"2026-08-12T04:18:47.702863626Z","published":"2026-08-10T12:02:44.917Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68310.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/23a2b98e754da04e0e90314d5fa8ca44349590fb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6f99a5667c6c7c3e0da1d3c4dc8dfb103042609e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/871549814eb4da081f1e93cc0c7ea626a310a966"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8e9db062654a388d0fa587acbeeae68dd33eba41"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a031f454f14e3e76ad03bcb23918e1a82b4b0869"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68310.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68310"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e6d557a78b6016eee7b9cd6832343efd32cc0b27"},{"fixed":"23a2b98e754da04e0e90314d5fa8ca44349590fb"},{"fixed":"a031f454f14e3e76ad03bcb23918e1a82b4b0869"},{"fixed":"871549814eb4da081f1e93cc0c7ea626a310a966"},{"fixed":"6f99a5667c6c7c3e0da1d3c4dc8dfb103042609e"},{"fixed":"8e9db062654a388d0fa587acbeeae68dd33eba41"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68310.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.18.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68310.json"}}],"schema_version":"1.9.0"}
