An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-98497 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-2026-98497/ (Markdown: https://insights.sbomify.com/CVE-2026-98497/index.md)","id":"CVE-2026-98497","markdown":"https://insights.sbomify.com/CVE-2026-98497/index.md","name":"CVE-2026-98497","record":{"aliases":["BELL-CVE-2026-98497","DEBIAN-CVE-2026-98497","GHSA-jq4w-vj6x-gwh6","UBUNTU-CVE-2026-98497"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A bug in the Linux kernel mlx5e driver swaps IPv6 IPsec policy masks, allowing attackers to bypass IPsec security policies when prefix lengths differ.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5e: fix swapped IPv6 IPsec policy masks\n\nIPv6 XFRM policies may use different source and destination prefix\nlengths. mlx5e_ipsec_policy_mask() builds the corresponding masks\nindependently, but setup_fte_addr6() installs each mask in the opposite\naddress field.\n\nWhen the prefix lengths differ, this makes the source match use the\ndestination prefix and the destination match use the source prefix.
