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-2022-49153 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-2022-49153/ (Markdown: https://insights.sbomify.com/CVE-2022-49153/index.md)","id":"CVE-2022-49153","markdown":"https://insights.sbomify.com/CVE-2022-49153/index.md","name":"CVE-2022-49153","record":{"aliases":["DEBIAN-CVE-2022-49153","GHSA-g9g4-w2mf-449q","UBUNTU-CVE-2022-49153"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel WireGuard","requires_auth":"low_privilege","summary":"A memory leak in the Linux kernel WireGuard module when IPv6 is disabled can lead to resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","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-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwireguard: socket: free skb in send6 when ipv6 is disabled\n\nI got a memory leak report:\n\nunreferenced object 0xffff8881191fc040 (size 232):\n  comm \"kworker/u17:0\", pid 23193, jiffies 4295238848 (age 3464.870s)\n  hex dump (first 32 bytes):\n    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................\n    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................\n  backtrace:\n    [\u003cffffffff814c3ef4\u003e] slab_post_alloc_hook+0x84/0x3b0\n    [\u003cffffffff814c8977\u003e] kmem_cache_alloc_node+0x167/0x340\n    [\u003cffffffff832974fb\u003e] __alloc_skb+0x1db/0x200\n    [\u003cffffffff82612b5d\u003e] wg_socket_send_buffer_to_peer+0x3d/0xc0\n    [\u003cffffffff8260e94a\u003e] wg_packet_send_handshake_initiation+0xfa/0x110\n    [\u003cffffffff8260ec81\u003e] wg_packet_handshake_send_worker+0x21/0x30\n    [\u003cffffffff8119c558\u003e] process_one_work+0x2e8/0x770\n    [\u003cffffffff8119ca2a\u003e] worker_thread+0x4a/0x4b0\n    [\u003cffffffff811a88e0\u003e] kthread+0x120/0x160\n    [\u003cffffffff8100242f\u003e] ret_from_fork+0x1f/0x30\n\nIn function wg_socket_send_buffer_as_reply_to_skb() or wg_socket_send_\nbuffer_to_peer(), the semantics of send6() is required to free skb.
