The Type6NasIe::Validate() function truncates a 32-bit length value to 16 bits, bypassing length validation and causing an out-of-bounds heap read in DecodeImeisv(), which can crash the AMF process.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://gist.github.com/hackeryounow/1c6741be7d536bd98434ac270dbb1f60","tags":[]},{"url":"https://github.com/openairinterface/oai-cn5g-amf/issues/16","tags":[]}],"exploitRefs":[{"url":"https://gist.github.com/hackeryounow/1c6741be7d536bd98434ac270dbb1f60","tags":[]},{"url":"https://github.com/openairinterface/oai-cn5g-amf/issues/16","tags":[]}],"hasPoc":true,"ai":null}
