Hi, The following vulnerability was published for ppp. CVE-2026-75883[0]: | 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 without checking the | available space and without implementing outgoing PEAP | fragmentation. Thus a pppd process connecting to a server which | requests PEAP authentication can be induced to corrupt global static | data following the outpacket_buf array, most likely causing | incorrect behavior or a crash. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
