Critical 9.8 CVSS Flaws in Qualcomm Chipsets Enable Remote Takeover

Qualcomm's May 2026 security bulletin discloses multiple high-severity vulnerabilities—notably CVE-2026-25254 (SocketIO improper authorization leading to remote code execution, CVSS 9.8), CVE-2026-25293 (PLC firmware authorization flaw causing a buffer overflow, CVSS 9.6), and CVE-2026-25262 (primary bootloader write-what-where via crafted ELF causing memory corruption)—affecting a broad set of Qualcomm chipsets and requiring OEM-distributed patches; remote RCEs risk large-scale compromise of smartphones and IoT devices while the bootloader flaw threatens boot integrity.
