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-2026-63873 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-2026-63873/ (Markdown: https://insights.sbomify.com/CVE-2026-63873/index.md)","id":"CVE-2026-63873","markdown":"https://insights.sbomify.com/CVE-2026-63873/index.md","name":"CVE-2026-63873","record":{"aliases":["BELL-CVE-2026-63873","DEBIAN-CVE-2026-63873","GHSA-fcmf-5wqg-hrw5","UBUNTU-CVE-2026-63873"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A reference leak in the AMD XDNA accelerator driver allows local attackers to exhaust kernel memory, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\naccel/amdxdna: Fix mm_struct reference leak in aie2_populate_range()\n\naie2_populate_range() jumps back to the again label without calling\nmmput(mm), leaking a reference to the mm_struct.\n\nAdd the missing mmput() before jumping to again.","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":"accel/amdxdna: Fix mm_struct reference leak in aie2_populate_range()","id":"CVE-2026-63873","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"net: mctp: usb: fix race between urb completion and rx_retry cancellation","id":"CVE-2026-63874"},"packages":[],"prev":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2026-63872"},"products":["Linux"],"published":"2026-07-19","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":"2026-07-19","vendors":["Linux"]},"summary":"A reference leak in the AMD XDNA accelerator driver allows local attackers to exhaust kernel memory, causing denial of service.","url":"https://insights.sbomify.com/CVE-2026-63873/"}
