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-2024-35969 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2024-35969/ (Markdown: https://insights.sbomify.com/CVE-2024-35969/index.md)","id":"CVE-2024-35969","markdown":"https://insights.sbomify.com/CVE-2024-35969/index.md","name":"CVE-2024-35969","record":{"aliases":["BELL-CVE-2024-35969","DEBIAN-CVE-2024-35969","GHSA-22hg-74mg-cj6f","UBUNTU-CVE-2024-35969"],"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":"none","summary":"A race condition in the Linux kernel IPv6 implementation can lead to a use-after-free, potentially causing a system crash or denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr\n\nAlthough ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it\nstill means hlist_for_each_entry_rcu can return an item that got removed\nfrom the list. The memory itself of such item is not freed thanks to RCU\nbut nothing guarantees the actual content of the memory is sane.\n\nIn particular, the reference count can be zero. This can happen if\nipv6_del_addr is called in parallel. ipv6_del_addr removes the entry\nfrom inet6_addr_lst (hlist_del_init_rcu(\u0026ifp-\u003eaddr_lst)) and drops all\nreferences (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough\ntiming, this can happen:\n\n1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry.\n\n2. Then, the whole ipv6_del_addr is executed for the given entry. The\n   reference count drops to zero and kfree_rcu is scheduled.\n\n3. ipv6_get_ifaddr continues and tries to increments the reference count\n   (in6_ifa_hold).\n\n4. The rcu is unlocked and the entry is freed.\n\n5. The freed entry is returned.\n\nPrevent increasing of the reference count in such case. The name\nin6_ifa_hold_safe is chosen to mimic the existing fib6_info_hold_safe.\n\n[   41.506330] refcount_t: addition on 0; use-after-free.\n[   41.506760] WARNING: CPU: 0 PID: 595 at lib/refcount.c:25 refcount_warn_saturate+0xa5/0x130\n[   41.507413] Modules linked in: veth bridge stp llc\n[   41.507821] CPU: 0 PID: 595 Comm: python3 Not tainted 6.9.0-rc2.main-00208-g49563be82afa #14\n[   41.508479] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996)\n[   41.509163] RIP: 0010:refcount_warn_saturate+0xa5/0x130\n[   41.509586] Code: ad ff 90 0f 0b 90 90 c3 cc cc cc cc 80 3d c0 30 ad 01 00 75 a0 c6 05 b7 30 ad 01 01 90 48 c7 c7 38 cc 7a 8c e8 cc 18 ad ff 90 \u003c0f\u003e 0b 90 90 c3 cc cc cc cc 80 3d 98 30 ad 01 00 0f 85 75 ff ff ff\n[   41.510956] RSP: 0018:ffffbda3c026baf0 EFLAGS: 00010282\n[   41.511368] RAX: 0000000000000000 RBX: ffff9e9c46914800 RCX: 0000000000000000\n[   41.511910] RDX: ffff9e9c7ec29c00 RSI: ffff9e9c7ec1c900 RDI: ffff9e9c7ec1c900\n[   41.512445] RBP: ffff9e9c43660c9c R08: 0000000000009ffb R09: 00000000ffffdfff\n[   41.512998] R10: 00000000ffffdfff R11: ffffffff8ca58a40 R12: ffff9e9c4339a000\n[   41.513534] R13: 0000000000000001 R14: ffff9e9c438a0000 R15: ffffbda3c026bb48\n[   41.514086] FS:  00007fbc4cda1740(0000) GS:ffff9e9c7ec00000(0000) knlGS:0000000000000000\n[   41.514726] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[   41.515176] CR2: 000056233b337d88 CR3: 000000000376e006 CR4: 0000000000370ef0\n[   41.515713] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n[   41.516252] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n[   41.516799] Call Trace:\n[   41.517037]  \u003cTASK\u003e\n[   41.517249]  ?
