AZL-103302 CVE-2026-75883 affecting package ppp 2.5.0-1

The code in pppd that formats a response to a PEAP Request packet in peapresponse copies an entire TLS record of up to 16384 bytes into the fixed global buffer outpacketbuf without checking the available space and without implementing outgoing PEAP fragmentation. Thus a pppd process connecting to...

DEBIAN-CVE-2026-90083

In the Linux kernel, the following vulnerability has been resolved: net/sched: actife: Only operate on Ethernet frames actife encapsulates/decapsulates the original Ethernet header and uses skb-dev-hardheaderlen as the length of that header. That is only correct for Ethernet devices: on a device...

kernel: ppp: require CAP_NET_ADMIN in target netns for unattached ioctls

A flaw was found in the Linux kernel's Point-to-Point Protocol PPP subsystem. A local unprivileged user can exploit this vulnerability by creating a new user namespace and bypassing authorization checks for unattached administrative input/output controls ioctls. This allows the user to perform...

CVE-2026-58095

mpEnddisc used incorrect length calculations when formatting endpoint discriminator addresses for display, allowing a received endpoint option to overflow a global result buffer. A malicious PPP peer can crash ppp8 or potentially execute arbitrary code as root...

CVE-2026-58096

LcpDecodeConfig did not validate the length of received endpoint discriminator options against the minimum required by RFC 1717. Undersized options would trigger an out-of-bounds write. A malicious PPP peer can exploit CVE-2026-58095 and CVE-2026-58096 to crash ppp8 or potentially execute arbitra...

CVE-2026-58097

mpSetEnddisc copied a user-supplied PSN endpoint value without length validation, allowing a buffer overflow via the ppp8 command interface. A local user with access to the ppp8 command interface can crash ppp8 or potentially execute arbitrary code as root...

CVE-2026-58097

The ppp(8) utility in FreeBSD contains a buffer overflow vulnerability in the mp_SetEnddisc() function. The flaw exists because the software copies a user-supplied PSN endpoint value without performing proper length validation via the ppp(8) command interface. A local user with access to this int...
