RHSA-2026:80675 PUBLISHED CVSS 6.900000095367432 MEDIUM

Record from redhat · Published October 12, 2026

A flaw in libxml2's xmlXPtrEvalXPtrPart function allows a local attacker to cause a heap-based buffer overflow. An integer overflow while processing an oversized xpointer() expression leads to incorrect memory allocation and an out-of-bounds write, potentially resulting in information disclosure, data corruption, or a denial of service (DoS).
