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-2026-64468 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-2026-64468/ (Markdown: https://insights.sbomify.com/CVE-2026-64468/index.md)","id":"CVE-2026-64468","markdown":"https://insights.sbomify.com/CVE-2026-64468/index.md","name":"CVE-2026-64468","record":{"aliases":["BELL-CVE-2026-64468","DEBIAN-CVE-2026-64468","GHSA-3g5w-3hx7-q6vh","ROOT-OS-DEBIAN-12-CVE-2026-64468","ROOT-OS-UBUNTU-2204-CVE-2026-64468","UBUNTU-CVE-2026-64468"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free in the Linux kernel binder driver allows local attackers to potentially execute code or escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbinder: fix UAF in binder_free_transaction()\n\nIn binder_free_transaction(), the t-\u003eto_proc is read under the t-\u003elock.\nHowever, once the t-\u003elock is dropped, the to_proc can die in parallel.\nThis leads to a use-after-free error when we attempt to acquire its\ninner lock right afterwards:\n\n  ==================================================================\n  BUG: KASAN: slab-use-after-free in _raw_spin_lock+0xe4/0x1a0\n  Write of size 4 at addr ffff00001125da70 by task B/672\n\n  CPU: 20 UID: 0 PID: 672 Comm: B Not tainted 7.1.0-rc6-00284-g8e65320d91cd #4 PREEMPT\n  Hardware name: linux,dummy-virt (DT)\n  Call trace:\n   _raw_spin_lock+0xe4/0x1a0\n   binder_free_transaction+0x8c/0x320\n   binder_send_failed_reply+0x21c/0x2f8\n   binder_thread_release+0x488/0x7e0\n   binder_ioctl+0x12c0/0x29a0\n  [...]\n\n  Allocated by task 675:\n   __kmalloc_cache_noprof+0x174/0x444\n   binder_open+0x118/0xb70\n   do_dentry_open+0x374/0x1040\n   vfs_open+0x58/0x3bc\n  [...]\n\n  Freed by task 212:\n   __kasan_slab_free+0x58/0x80\n   kfree+0x1a0/0x4a4\n   binder_proc_dec_tmpref+0x32c/0x5e0\n   binder_deferred_func+0xc48/0x104c\n   process_one_work+0x53c/0xbc0\n  [...]\n  ==================================================================\n\nTo prevent this, pin the target thread (t-\u003eto_thread) to guarantee the\ntarget process remains alive.
