CVE-2026-25277 is a critical memory corruption vulnerability in Qualcomm Secure Processor firmware used to implement StrongBox functionality on affected platforms. The flaw is classified as CWE-120 and results from copying attacker-controlled input into a buffer without validating that the input length fits the destination buffer. Public reporting describes the issue as occurring while using StrongBox, indicating the vulnerable code path is within the Secure Processing Unit firmware that underpins hardware-backed key management and related cryptographic operations. A successful trigger can overwrite adjacent memory inside the isolated secure processor environment, causing memory corruption and potentially enabling further compromise of StrongBox security boundaries.
