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-2026-53292 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-53292/ (Markdown: https://insights.sbomify.com/CVE-2026-53292/index.md)","id":"CVE-2026-53292","markdown":"https://insights.sbomify.com/CVE-2026-53292/index.md","name":"CVE-2026-53292","record":{"aliases":["AZL-91317","BELL-CVE-2026-53292","DEBIAN-CVE-2026-53292","GHSA-mfj5-8wwq-98rr","ROOT-OS-DEBIAN-11-CVE-2026-53292","ROOT-OS-DEBIAN-12-CVE-2026-53292","ROOT-OS-DEBIAN-13-CVE-2026-53292","ROOT-OS-UBUNTU-2204-CVE-2026-53292","ROOT-OS-UBUNTU-2404-CVE-2026-53292","UBUNTU-CVE-2026-53292"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can trigger a kernel panic in the Phonet socket implementation by sending a specific message, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: phonet: do not BUG_ON() in pn_socket_autobind() on failed bind\n\nsyzbot reported a kernel BUG triggered from pn_socket_sendmsg() via\npn_socket_autobind():\n\n  kernel BUG at net/phonet/socket.c:213!\n  RIP: 0010:pn_socket_autobind net/phonet/socket.c:213 [inline]\n  RIP: 0010:pn_socket_sendmsg+0x240/0x250 net/phonet/socket.c:421\n  Call Trace:\n   sock_sendmsg_nosec+0x112/0x150 net/socket.c:797\n   __sock_sendmsg net/socket.c:812 [inline]\n   __sys_sendto+0x402/0x590 net/socket.c:2280\n   ...\n\npn_socket_autobind() calls pn_socket_bind() with port 0 and, on\n-EINVAL, assumes the socket was already bound and asserts that the\nport is non-zero:\n\n  err = pn_socket_bind(sock, ..., sizeof(struct sockaddr_pn));\n  if (err != -EINVAL)\n          return err;\n  BUG_ON(!pn_port(pn_sk(sock-\u003esk)-\u003esobject));\n  return 0; /* socket was already bound */\n\nHowever pn_socket_bind() also returns -EINVAL when sk-\u003esk_state is not\nTCP_CLOSE, even when the socket has never been bound and pn_port() is\nstill 0.
