CVE-2026-85977

Name of the Vulnerable Software and Affected Versions libtirpc (affected versions not specified)

Description A flaw exists where a remote attacker can trigger a Denial of Service (DoS) by sending specially crafted PMAPPROC DUMP replies to a client application. This occurs when the application uses the pmap getmaps() function against a host controlled by the attacker. The issue stems from unbounded decoding, which leads to excessive CPU and memory allocation, resulting in resource exhaustion for the client process.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
