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-2026-89717 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-2026-89717/ (Markdown: https://insights.sbomify.com/CVE-2026-89717/index.md)","id":"CVE-2026-89717","markdown":"https://insights.sbomify.com/CVE-2026-89717/index.md","name":"CVE-2026-89717","record":{"aliases":["AZL-100539","BELL-CVE-2026-89717","DEBIAN-CVE-2026-89717","GHSA-5wpf-6ffc-hwm4","UBUNTU-CVE-2026-89717"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel zram","requires_auth":"low_privilege","summary":"A null pointer dereference in the Linux kernel zram module can cause a system crash when accessing compressor settings after destruction.","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\nzram: set default primary compressor in zram_destroy_comps()\n\nPatch series \"zram: fix zram issues reported by sashiko\".\n\nSashiko drove by and reported [1] a couple of zram issues:\na possible BUG_ON() in zlib code due to missing winbits range\nvalidation and one possible NULL-ptr dereference in zcomp.\nBoth are low risk yet still worth fixing.\n\nThis patch (of 2):\n\nzram_destroy_comps() resets all compressors and leaves them set to NULL,\nincluding the primary one, which is invalid device state, as now\ncomp_algorithm_show()-\u003estrcmp() can be called on a NULL compressor.
