It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-68304 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-68304/ (Markdown: https://insights.sbomify.com/CVE-2026-68304/index.md)","id":"CVE-2026-68304","markdown":"https://insights.sbomify.com/CVE-2026-68304/index.md","name":"CVE-2026-68304","record":{"aliases":["BELL-CVE-2026-68304","DEBIAN-CVE-2026-68304","GHSA-gqh4-q6g4-cvr4","UBUNTU-CVE-2026-68304"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A local attacker can trigger a kernel warning and potential denial of service in the brcmfmac Wi-Fi driver by configuring 802.1X-SHA256 authentication.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: brcmfmac: fix 802.1X-SHA256 call trace warning\n\nBased on wpa_auth as 1x_256 mode, need to set up\n\"use_fwsup\" with BRCMF_PROFILE_FWSUP_1X.\nOr it will happen trace warning when call brcmf_cfg80211_set_pmk().\n\n[ 4481.831101] ------------[ cut here ]------------\n[ 4481.831102] WARNING: CPU: 1 PID: 2997 at\ndrivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:7242 brcmf_cfg80211_set_pmk+0x77/0xd0 [brcmfmac]\n[...]\n[ 4481.831202] Call Trace:\n[ 4481.831204]  \u003cTASK\u003e\n[ 4481.831205]  nl80211_set_pmk+0x183/0x250 [cfg80211]\n[ 4481.831233]  genl_family_rcv_msg_doit+0xea/0x150\n[ 4481.831237]  genl_rcv_msg+0x104/0x240\n[ 4481.831239]  ? cfg80211_probe_status+0x2c0/0x2c0 [cfg80211]\n[ 4481.831257]  ? genl_family_rcv_msg_doit+0x150/0x150\n[ 4481.831259]  netlink_rcv_skb+0x4e/0x100\n[ 4481.831261]  genl_rcv+0x24/0x40\n[ 4481.831262]  netlink_unicast+0x236/0x380\n[ 4481.831264]  netlink_sendmsg+0x250/0x4b0\n[ 4481.831266]  sock_sendmsg+0x5c/0x70\n[ 4481.831269]  ____sys_sendmsg+0x236/0x2b0\n[ 4481.831271]  ? copy_msghdr_from_user+0x6d/0xa0\n[ 4481.831272]  ___sys_sendmsg+0x86/0xd0\n[ 4481.831274]  ? avc_has_perm+0x8c/0x1a0\n[ 4481.831276]  ? preempt_count_add+0x6a/0xa0\n[ 4481.831279]  ? sock_has_perm+0x82/0xa0\n[ 4481.831280]  __sys_sendmsg+0x57/0xa0\n[ 4481.831282]  do_syscall_64+0x38/0x90\n[ 4481.831284]  entry_SYSCALL_64_after_hwframe+0x63/0xcd\n[ 4481.831286] RIP: 0033:0x7fd270d369b4","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"wifi: brcmfmac: fix 802.1X-SHA256 call trace warning","id":"CVE-2026-68304","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"drm/xe/vf: Add drm_dev guards when detaching CCS read/write buffers","id":"CVE-2026-68305"},"packages":[],"prev":{"headline":"drm/vc4: hvs/v3d: Fix null dereference in unbind","id":"CVE-2026-68303"},"products":["Linux"],"published":"2026-08-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-19","vendors":["Linux"]},"summary":"A local attacker can trigger a kernel warning and potential denial of service in the brcmfmac Wi-Fi driver by configuring 802.1X-SHA256 authentication.","url":"https://insights.sbomify.com/CVE-2026-68304/"}
