CVE-2026-16529
Estado: Pendiente de análisisAlta (7.5)—
A signed integer overflow in the PCP __pmGetPDU() function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service (DoS) for subsequent packet reads.
CVSS
