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-2025-68732 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-2025-68732/ (Markdown: https://insights.sbomify.com/CVE-2025-68732/index.md)","id":"CVE-2025-68732","markdown":"https://insights.sbomify.com/CVE-2025-68732/index.md","name":"CVE-2025-68732","record":{"aliases":["AZL-73072","BELL-CVE-2025-68732","DEBIAN-CVE-2025-68732","GHSA-4c9c-638j-jrpm","ROOT-OS-DEBIAN-12-CVE-2025-68732","ROOT-OS-UBUNTU-2204-CVE-2025-68732","ROOT-OS-UBUNTU-2404-CVE-2025-68732","UBUNTU-CVE-2025-68732"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel host1x driver allows local attackers to cause denial of service or potentially escalate privileges.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ngpu: host1x: Fix race in syncpt alloc/free\n\nFix race condition between host1x_syncpt_alloc()\nand host1x_syncpt_put() by using kref_put_mutex()\ninstead of kref_put() + manual mutex locking.\n\nThis ensures no thread can acquire the\nsyncpt_mutex after the refcount drops to zero\nbut before syncpt_release acquires it.\nThis prevents races where syncpoints could\nbe allocated while still being cleaned up\nfrom a previous release.\n\nRemove explicit mutex locking in syncpt_release\nas kref_put_mutex() handles this atomically.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"gpu: host1x: Fix race in syncpt alloc/free","id":"CVE-2025-68732","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2025"},"n_packages":0,"n_references":7,"next":{"headline":"smack: fix bug: unprivileged task can create labels","id":"CVE-2025-68733"},"packages":[],"prev":{"headline":"accel/amdxdna: Fix an integer overflow in aie2_query_ctx_status_array()","id":"CVE-2025-68731"},"products":["Linux"],"published":"2025-12-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A race condition in the Linux kernel host1x driver allows local attackers to cause denial of service or potentially escalate privileges.","url":"https://insights.sbomify.com/CVE-2025-68732/"}
