CVE-2026-25291: Qualcomm memory corruption in shared page list synchronization

CVE-2026-25291 · Severity: high · CVSS 7.8 · Published 2026-10-06

A memory corruption vulnerability in Qualcomm components affects the handling of shared memory page lists when multiple operations run simultaneously. Without proper synchronization, an attacker with local access could corrupt memory, potentially leading to system crashes, information disclosure, or privilege escalation depending on what data is corrupted.

Technologies: Qualcomm <UNKNOWN>. Vendors: Qualcomm.
