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-2026-74320 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-2026-74320/ (Markdown: https://insights.sbomify.com/CVE-2026-74320/index.md)","id":"CVE-2026-74320","markdown":"https://insights.sbomify.com/CVE-2026-74320/index.md","name":"CVE-2026-74320","record":{"aliases":["BELL-CVE-2026-74320","DEBIAN-CVE-2026-74320","GHSA-cprm-m4x6-j7h5","UBUNTU-CVE-2026-74320"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A use-after-free and buffer overrun in the Linux kernel sm501fb driver allows local attackers to execute code or cause a system crash.","user_interaction":"not_required","vuln_class":"use_after_free"},"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\nfbdev: sm501fb: Fix buffer errors in OF binding code\n\nThe code that gets the frame buffer mode from OF has 'use after free',\n'buffer overrun' and memory leaks.\n\ninfo-\u003eedid_data isn't free if the probe functions fail or if\npd-\u003edef_mode is set.\n\nIf both the CRT and PANEL are enabled info-\u003eedid_data is used after\nbeing freed and is freed twice.\n\nThe string returned by of_get_property(np, \"mode\", \u0026len) is just\nwritten over either the static \"640x480-16@60\" or the module parameter\nstring without any regard for the length (which is most likely longer).\n\nUse kstrump() for the OF mode and free everything before freeing 'info.","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":"fbdev: sm501fb: Fix buffer errors in OF binding code","id":"CVE-2026-74320","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"btrfs: fix invalid pointer dereference in __btrfs_run_delayed_refs()","id":"CVE-2026-74321"},"packages":[],"prev":{"headline":"btrfs: zoned: fix deadlock waiting for ticket during data relocation","id":"CVE-2026-74319"},"products":["Linux"],"published":"2026-08-15","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 use-after-free and buffer overrun in the Linux kernel sm501fb driver allows local attackers to execute code or cause a system crash.","url":"https://insights.sbomify.com/CVE-2026-74320/"}
