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-2025-68362 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-2025-68362/ (Markdown: https://insights.sbomify.com/CVE-2025-68362/index.md)","id":"CVE-2025-68362","markdown":"https://insights.sbomify.com/CVE-2025-68362/index.md","name":"CVE-2025-68362","record":{"aliases":["AZL-73063","BELL-CVE-2025-68362","DEBIAN-CVE-2025-68362","GHSA-x793-gh9g-39hm","ROOT-OS-DEBIAN-11-CVE-2025-68362","ROOT-OS-DEBIAN-12-CVE-2025-68362","ROOT-OS-DEBIAN-13-CVE-2025-68362","ROOT-OS-UBUNTU-2204-CVE-2025-68362","ROOT-OS-UBUNTU-2404-CVE-2025-68362","UBUNTU-CVE-2025-68362"],"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":"none","summary":"A buffer underflow in the rtl8187 WiFi driver allows attackers to cause a kernel panic via truncated packets, requiring a patch.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nwifi: rtl818x: rtl8187: Fix potential buffer underflow in rtl8187_rx_cb()\n\nThe rtl8187_rx_cb() calculates the rx descriptor header address\nby subtracting its size from the skb tail pointer.\nHowever, it does not validate if the received packet\n(skb-\u003elen from urb-\u003eactual_length) is large enough to contain this\nheader.\n\nIf a truncated packet is received, this will lead to a buffer\nunderflow, reading memory before the start of the skb data area,\nand causing a kernel panic.\n\nAdd length checks for both rtl8187 and rtl8187b descriptor headers\nbefore attempting to access them, dropping the packet cleanly if the\ncheck fails.","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":"wifi: rtl818x: rtl8187: Fix potential buffer underflow in rtl8187_rx_cb()","id":"CVE-2025-68362","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":8,"next":{"headline":"bpf: Check skb-\u003etransport_header is set in bpf_skb_check_mtu","id":"CVE-2025-68363"},"packages":[],"prev":{"headline":"erofs: limit the level of fs stacking for file-backed mounts","id":"CVE-2025-68361"},"products":["Linux"],"published":"2025-12-24","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":"2026-05-11","vendors":["Linux"]},"summary":"A buffer underflow in the rtl8187 WiFi driver allows attackers to cause a kernel panic via truncated packets, requiring a patch.","url":"https://insights.sbomify.com/CVE-2025-68362/"}
