{"id":"AZL-103302","summary":"CVE-2026-75883 affecting package ppp 2.5.0-1","details":"The code in pppd that formats a response to a PEAP Request packet in peap_response() copies an entire TLS record of up to 16384 bytes into the fixed global buffer outpacket_buf\n without checking the available space and without implementing outgoing \nPEAP fragmentation. Thus a pppd process connecting to a server which \nrequests PEAP authentication can be induced to corrupt global static \ndata following the outpacket_buf array, most likely causing incorrect behavior or a crash.","modified":"2026-09-19T14:16:12.639321597Z","published":"2026-09-18T16:17:09Z","upstream":["CVE-2026-75883"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-75883"}],"affected":[{"package":{"name":"ppp","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/ppp"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.5.0-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-103302.json"}}],"schema_version":"1.9.0"}
