{"id":"CVE-2026-43630","summary":"llama.cpp b5702–b7653 Out-of-Bounds Read Information Disclosure","details":"llama.cpp builds b5702 through b7653 contain an out-of-bounds read vulnerability in the recurrent memory state restore path that allows attackers with write access to the slot save directory to read memory past the end of the allocated cells array. Attackers can craft a malicious slot file with an oversized seq_id value to trigger an out-of-bounds read that leaks heap data including pointer values into server logs, defeating ASLR protections and facilitating further exploitation.","modified":"2026-08-08T09:31:01.622889Z","published":"2026-08-06T15:50:55.022Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-125","CWE-209"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43630.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43630.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43630"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/llama-cpp-b5702-b7653-out-of-bounds-read-information-disclosure"},{"type":"FIX","url":"https://github.com/ggml-org/llama.cpp/commit/f93c09e2673090b59802f2552848a1cac70598b0"},{"type":"PACKAGE","url":"https://github.com/Vladimir-tokarev-cyera/llama-cpp-security-patches"},{"type":"PACKAGE","url":"https://github.com/ggml-org/llama.cpp"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ggml-org/llama.cpp","events":[{"introduced":"edc4a29effe716956fdfd2bc5b9cba2a6d8492f8"},{"fixed":"193ee38a1bc2aed807823112cf030edcae186892"},{"fixed":"f93c09e2673090b59802f2552848a1cac70598b0"}],"database_specific":{"extracted_events":[{"introduced":"b5702"},{"fixed":"b7653"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["0.17.1","b8485","b8480","b8479","b8478","b8477","b8476","b8475","b8474","b8473","b8472","b8471","b8470","b8469","b8468","b8467","b8466","b8464","b8461","b8460","b8459","b8457","b8445","b8429","b8425","b8424","b8423","b8422","b8420","b8419","b8418","b8417","b8416","b8413","b8412","b8411","b8407","b8405","b8401","b8400","b8399","b8398","b8394","b8393","b8392","b8391","b8390","b8389","b8388","b8377","b8373","b8372","b8370","b8369","b8368","b8366","b8364","b8363","b8362","b8361","b8360","b8358","b8356","b8355","b8354","b8353","b8352","b8351","b8350","b8348","b8347","b8325","b8339","b8340","b8338","b8334","b8337","b8336","b8333","b8332","b8331","b8330","b8329","b8328","b8327","b8323","b8322","b8320","b8318","b8317","b8315","b8312","b8310","b8309","b8308","b8305","b8304","b8303","b8301","b8300","b8299","b8298","b8297","b8295","b8292","b8291","b8287","b8286","b8285","b8284","b8281","b8280","b8279","b8278","b8277","b8276","b8272","b8271","b8270","b8269","b8268","b8267","b8266","b8265","b8264","b8263","b8262","b8261","b8260","b8259","b8258","b8256","b8255","b8254","b8253","b8252","b8250","b8249","b8248","b8247","b8246","b8245","b8244","b8243","b8242","b8241","b8240","b8239","b8238","b8236","b8235","b8234","b8233","b8232","b8231","b8230","b8229","b8227","b8226","b8225","b8224","b8223","b8222","b8221","b8220","b8219","b8218","b8216","b8215","b8214","b8213","b8212","b8210","b8209","b8208","b8204","b8203","b8202","b8201","b8200","b8198","b8197","b8196","b8195","b8194","b8193","b8192","b8191","b8190","b8189","b8188","b8187","b8185","b8184","b8183","b8182","b8181","b8180","b8179","b8178","b8177","b8175","gguf-v0.18.0","b8173","b8172","b8171","b8170","b8169","b8168","b8167","b8166","b8165","b8164","b8163","b8162","b8161","b8159","b8157","b8156","b8155","b8153","b8152","b8149","b8148","b8147","b8146","b8145","b8144","b8143","b8142","b8141","b8140","b8138","b8133","b8132","b8131","b8130","b8128","b8126","b8124","b8123","b8122","b8121","b8119","b8118","b8117","b8116","b8115","b8113","b8112","b8111","b8110","b8109","b8108","b8107","b8106","b8105","b8104","b8102","b8101","b8100","b8099","b8098","b8096","b8095","b8094","b8093","b8091","b8089","b8088","b8087","b8086","b8083","b8082","b8079","b8078","b8077","b8076","b8075","b8074","b8073","b8072","b8071","b8070","b8069","b8068","b8067","b8064","b8062","b8061","b8060","b8059","b8058","b8057","b8056","b8055","b8054","b8053","b8052","b8051","b8049","b8048","b8047","b8046","b8043","b8042","b8041","b8040","b8038","b8037","b8036","b8035","b8034","b8033","b8032","b8030","b8028","b8027","b8026","b8025","b8024","b8023","b8022","b8021","b8020","b8018","b8017","b8012","b8011","b8008","b8007","b8006","b8005","b8004","b8003","b8001","b7999","b7998","b7997","b7996","b7995","b7994","b7993","b7992","b7991","b7990","b7989","b7988","b7987","b7984","b7983","b7982","b7981","b7976","b7974","b7973","b7972","b7971","b7970","b7969","b7968","b7966","b7965","b7964","b7962","b7961","b7960","b7959","b7958","b7957","b7956","b7955","b7954","b7952","b7951","b7950","b7946","b7947","b7945","b7944","b7943","b7942","b7941","b7940","b7938","b7936","b7935","b7933","b7932","b7931","b7930","b7929","b7928","b7927","b7926","b7925","b7924","b7923","b7922","b7921","b7920","b7919","b7918","b7917","b7913","b7911","b7910","b7909","b7907","b7905","b7904","b7903","b7902","b7899","b7898","b7895","b7897","b7896","b7885","b7883","b7881","b7880","b7879","b7876","b7875","b7872","b7871","b7870","b7869","b7868","b7867","b7865","b7864","b7862","b7861","b7860","b7858","b7857","b7856","b7855","b7853","b7852","b7851","b7850","b7849","b7847","b7845","b7844","b7843","b7842","b7841","b7839","b7837","b7836","b7835","b7833","b7832","b7830","b7828","b7827","b7826","b7825","b7824","b78
