CVE-2026-47128 nono: Sandbox escape on Linux via D-Bus: `systemd-run --user`

nono is software that allows users to run AI agents in a zero-latency sandbox. Prior to version 0.55.0, the nono Landlock/seccomp policies allow access to local Unix domain sockets concrete and abstract. This allows an easy sandbox escape by talking to the per-user systemd dbus socket. Version...

p11-kit: Stack exhaustion via unbounded recursion in RPC attribute parsing

A flaw was found in p11-kit. The RPC message attribute parsing functions p11rpcmessagegetattribute and p11rpcmessagegetattributearrayvalue form a mutually-recursive call chain with no recursion depth limit when processing nested CKAWRAPTEMPLATE, CKAUNWRAPTEMPLATE, and CKADERIVETEMPLATE attributes...

CVE-2026-54776

CoreWCF (UnixDomainSocket transport) with PosixIdentity client credentials is affected by a vulnerability where connections can bypass the framing-layer identity checks by skipping the application/unixposix stream upgrade before message dispatch. Affected versions include CoreWCF prior to 1.8.1 a...

postgresql: PostgreSQL: Denial of Service via uncontrolled recursion in SSL/GSS negotiation

A flaw was found in PostgreSQL. Uncontrolled recursion during SSL Secure Sockets Layer and GSS Generic Security Service negotiation allows an attacker to achieve a sustained denial of service. This can be exploited by an attacker with access to a PostgreSQL AFUNIX socket. If SSL and GSS are both...
