A remote attacker can exploit this vulnerability by sending specially crafted PMAPPROC_DUMP replies to a client application that uses the pmap_getmaps() function against an attacker-controlled host. This unbounded decoding can lead to excessive memory and CPU allocation, causing the client process to experience a Denial of Service (DoS) due to resource exhaustion.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-1050"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:80360","tags":[]},{"url":"https://access.redhat.com/security/cve/CVE-2026-85977","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2478979","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
