{"id":"CVE-2026-23060","summary":"crypto: authencesn - reject too-short AAD (assoclen\u003c8) to match ESP/ESN spec","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: authencesn - reject too-short AAD (assoclen\u003c8) to match ESP/ESN spec\n\nauthencesn assumes an ESP/ESN-formatted AAD. When assoclen is shorter than\nthe minimum expected length, crypto_authenc_esn_decrypt() can advance past\nthe end of the destination scatterlist and trigger a NULL pointer dereference\nin scatterwalk_map_and_copy(), leading to a kernel panic (DoS).\n\nAdd a minimum AAD length check to fail fast on invalid inputs.","modified":"2026-04-02T17:29:40.655382Z","published":"2026-02-04T16:07:42.860Z","related":["SUSE-SU-2026:0928-1","SUSE-SU-2026:0961-1","SUSE-SU-2026:0962-1","SUSE-SU-2026:0984-1","SUSE-SU-2026:1003-1","SUSE-SU-2026:1041-1","SUSE-SU-2026:1077-1","SUSE-SU-2026:1078-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:1131-1","SUSE-SU-2026:20667-1","SUSE-SU-2026:20720-1","SUSE-SU-2026:20838-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23060.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/161bdc90fce25bd9890adc67fa1c8563a7acbf40"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2397e9264676be7794f8f7f1e9763d90bd3c7335"},{"type":"WEB","url":"https://git.kernel.org/stable/c/767e8349f7e929b7dd95c08f0b4cb353459b365e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9532ff0d0e90ff78a214299f594ab9bac81defe4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b0a9609283a5c852addb513dafa655c61eebc1ef"},{"type":"WEB","url":"https://git.kernel.org/stable/c/df22c9a65e9a9daa368a72fed596af9d7d5876bb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fee86edf5803f1d1f19e3b4f2dacac241bddfa48"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23060.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23060"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"104880a6b470958ddc30e139c41aa4f6ed3a5234"},{"fixed":"df22c9a65e9a9daa368a72fed596af9d7d5876bb"},{"fixed":"fee86edf5803f1d1f19e3b4f2dacac241bddfa48"},{"fixed":"767e8349f7e929b7dd95c08f0b4cb353459b365e"},{"fixed":"b0a9609283a5c852addb513dafa655c61eebc1ef"},{"fixed":"161bdc90fce25bd9890adc67fa1c8563a7acbf40"},{"fixed":"9532ff0d0e90ff78a214299f594ab9bac81defe4"},{"fixed":"2397e9264676be7794f8f7f1e9763d90bd3c7335"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23060.json"}}],"schema_version":"1.7.5"}
