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-2026-68144 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-2026-68144/ (Markdown: https://insights.sbomify.com/CVE-2026-68144/index.md)","id":"CVE-2026-68144","markdown":"https://insights.sbomify.com/CVE-2026-68144/index.md","name":"CVE-2026-68144","record":{"aliases":["BELL-CVE-2026-68144","DEBIAN-CVE-2026-68144","GHSA-362p-g3rp-mxch","UBUNTU-CVE-2026-68144"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel's Phonet protocol allows attackers to potentially execute code or escalate privileges via crafted network packets.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nphonet: pep: fix use-after-free in pep_get_sb()\n\npep_get_sb() doesn't consider that pskb_may_pull() might have relocated\nthe skb data, and continue to access the older pointer, causing UAF.\n\nReproduced under KASAN:\n\n  BUG: KASAN: slab-use-after-free in pep_get_sb+0x234/0x3b0\n  Read of size 1 at addr ff11000105510f50 by task repro/157\n   pep_get_sb+0x234/0x3b0\n   pipe_handler_do_rcv+0x5f7/0xa10\n   pep_do_rcv+0x203/0x410\n   __sk_receive_skb+0x471/0x4a0\n   phonet_rcv+0x5b3/0x6c0\n   __netif_receive_skb+0xcc/0x1d0\n\nRefetch the header with skb_header_pointer() after pskb_may_pull(), so\nthe possibly stale pointer is no longer dereferenced.
