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-2026-93236 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-2026-93236/ (Markdown: https://insights.sbomify.com/CVE-2026-93236/index.md)","id":"CVE-2026-93236","markdown":"https://insights.sbomify.com/CVE-2026-93236/index.md","name":"CVE-2026-93236","record":{"aliases":["BELL-CVE-2026-93236","DEBIAN-CVE-2026-93236","GHSA-24fx-cxxf-wpf5","UBUNTU-CVE-2026-93236"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel media driver","requires_auth":"low_privilege","summary":"A local attacker can cause a kernel crash by triggering a NULL pointer dereference in the Meson video decoder driver when using unsupported pixel formats.","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\nmedia: meson: vdec: fix NULL pointer deref in vdec_try_fmt_common\n\nWhen VIDIOC_TRY_FMT is called with an unsupported pixel format on the\nOUTPUT queue, vdec_try_fmt_common() falls back to V4L2_PIX_FMT_MPEG2.\nHowever, if a distro has locally patched MPEG2 support out (as it has\nbeen broken for some time) the platform format table does not contain\nMPEG2 so find_format() returns NULL and the subsequent dereference of\nfmt_out-\u003emax_width triggers a NULL pointer dereference.\n\nFix this by falling back to the first format in the platform's format\narray instead of hardcoding V4L2_PIX_FMT_MPEG2.
