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-2026-64484 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-2026-64484/ (Markdown: https://insights.sbomify.com/CVE-2026-64484/index.md)","id":"CVE-2026-64484","markdown":"https://insights.sbomify.com/CVE-2026-64484/index.md","name":"CVE-2026-64484","record":{"aliases":["BELL-CVE-2026-64484","DEBIAN-CVE-2026-64484","GHSA-783r-hxwf-2cjj","ROOT-OS-UBUNTU-2204-CVE-2026-64484","UBUNTU-CVE-2026-64484"],"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":"none","summary":"A missing null check in the ALSA es1938 driver can cause a kernel crash via null pointer dereference during memory allocation failure.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nALSA: es1938: check snd_ctl_new1() return value\n\nsnd_ctl_new1() can return NULL when memory allocation fails.\nsnd_es1938_mixer() does not check the return value before dereferencing\nthe pointer, which can lead to a NULL pointer dereference.\n\nAdd a NULL check after snd_ctl_new1() and return -ENOMEM if it fails.","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":"ALSA: es1938: check snd_ctl_new1() return value","id":"CVE-2026-64484","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"ALSA: compress: Fix task creation error unwind","id":"CVE-2026-64485"},"packages":[],"prev":{"headline":"ALSA: firewire: isight: bound the sample count to the packet payload","id":"CVE-2026-64483"},"products":["Linux"],"published":"2026-07-25","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":"2026-08-17","vendors":["Linux"]},"summary":"A missing null check in the ALSA es1938 driver can cause a kernel crash via null pointer dereference during memory allocation failure.","url":"https://insights.sbomify.com/CVE-2026-64484/"}
