An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-74678 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-2026-74678/ (Markdown: https://insights.sbomify.com/CVE-2026-74678/index.md)","id":"CVE-2026-74678","markdown":"https://insights.sbomify.com/CVE-2026-74678/index.md","name":"CVE-2026-74678","record":{"aliases":["AZL-97359","BELL-CVE-2026-74678","DEBIAN-CVE-2026-74678","GHSA-5prv-rfcq-7r84","UBUNTU-CVE-2026-74678"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"none","summary":"A memory leak in the Linux kernel's ax88179_178a USB network driver can cause resource exhaustion and denial of service under memory pressure.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: usb: ax88179_178a: fix skb leak in ax88179_tx_fixup()\n\nWhen the interface has NETIF_F_SG enabled and skb_linearize() fails in\nax88179_tx_fixup(), the function returns NULL without freeing the skb.\n\nusbnet_start_xmit() treats a NULL return from tx_fixup() as a drop\n(info-\u003eflags does not set FLAG_MULTI_PACKET for this driver), jumping\nto the \"drop\" label where it does `if (skb) dev_kfree_skb_any(skb)`.\nBecause tx_fixup() returned NULL, the local skb variable in\nusbnet_start_xmit() is NULL, so the original skb is never freed — a\nmemory leak on every TX frame whose linearization fails (i.e. under\nmemory pressure).\n\nFree the skb before returning, matching the error handling already used\nfor the pskb_expand_head() failure path in the same function.","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":"net: usb: ax88179_178a: fix skb leak in ax88179_tx_fixup()","id":"CVE-2026-74678","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"usb: gadget: f_ncm: Use unsigned int for ndp_index","id":"CVE-2026-74679"},"packages":[],"prev":{"headline":"net: usb: ipheth: fix carrier_work UAF on disconnect","id":"CVE-2026-74677"},"products":["Linux"],"published":"2026-08-22","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel's ax88179_178a USB network driver can cause resource exhaustion and denial of service under memory pressure.","url":"https://insights.sbomify.com/CVE-2026-74678/"}
