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-2026-80605 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-2026-80605/ (Markdown: https://insights.sbomify.com/CVE-2026-80605/index.md)","id":"CVE-2026-80605","markdown":"https://insights.sbomify.com/CVE-2026-80605/index.md","name":"CVE-2026-80605","record":{"aliases":["BELL-CVE-2026-80605","DEBIAN-CVE-2026-80605","GHSA-g689-gjw8-39fq","UBUNTU-CVE-2026-80605"],"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 local attacker with access to the picolcd HID device can trigger a kernel crash via integer overflow leading to NULL pointer dereference.","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\nHID: picolcd: prevent NULL pointer dereference in picolcd_send_and_wait()\n\nIn picolcd_send_and_wait(), an integer overflow of the signed loop counter\n'k' can theoretically lead to a NULL pointer dereference of 'raw_data'.\nIf the loop executes more than INT_MAX times, 'k' becomes negative,\nmaking the condition 'k \u003c size' true even when 'size' is 0.\n\nChange the type of 'k' to 'unsigned int' to prevent the overflow and\neliminate the out-of-bounds access.\n\nFound by Linux Verification Center (linuxtesting.org) with the Svace static\nanalysis tool.\n\n[jkosina@suse.com: extended hash length]","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":"HID: picolcd: prevent NULL pointer dereference in picolcd_send_and_wait()","id":"CVE-2026-80605","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":"drm/xe/userptr: Hold notifier_lock for write on inject test path","id":"CVE-2026-80606"},"packages":[],"prev":{"headline":"HID: core: Fix OOB read in hid_get_report for numbered reports","id":"CVE-2026-80604"},"products":["Linux"],"published":"2026-08-28","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":"2026-08-28","vendors":["Linux"]},"summary":"A local attacker with access to the picolcd HID device can trigger a kernel crash via integer overflow leading to NULL pointer dereference.","url":"https://insights.sbomify.com/CVE-2026-80605/"}
