The CVE-2025-64314 vulnerability stems from improper permission enforcement within the memory management module of Huawei systems. Memory management modules control allocation, deallocation, and access rights for memory regions. This flaw allows unauthorized bypass of read, write, or execute protections on memory. Attackers with local system access can exploit it without privileges or user interaction. The vulnerability likely resides in kernel-level code handling memory protection mechanisms. It may involve faulty checks in functions like mprotect or mmap. Exploitation involves crafting operations to access restricted memory areas. This can lead to reading sensitive data or writing to critical memory. The CVSS 3.1 vector indicates local attack vector and low complexity. Scope change suggests impact beyond the immediate security domain. High confidentiality impact means potential data disclosure. High integrity and availability impact enable system compromise. Exploits could use malicious apps or scripts manipulating memory. The flaw might break isolation between processes or spaces. Successful exploitation can result in privilege escalation. It could allow arbitrary code execution in kernel context. Memory corruption or leakage is a likely outcome. Huawei devices with affected software versions are vulnerable. The issue underscores critical memory safety requirements. Patches are necessary to rectify permission checks.
