CVE-2025-47373: About Qualcomm – Fixed a typical type Confusion or an Improper Bounds Check within the firmware’s protocol stack. (5th Mar 2026)
Preface: 5G Timing Advance (TA) invocation is a mechanism where the base station (gNB) instructs user equipment (UE) to advance its uplink transmission timing to compensate for signal propagation delays. This synchronization ensures that signals from UEs at different distances arrive at the gNB within the same time slot, preventing interference. Background: In the 5G…

CVE-2025-47378: Exposure of Sensitive System Information to an Unauthorized Control Sphere in HLOS – Cryptographic Issue when a shared VM reference (4th Mar 2026)
Preface: Qualcomm’s pVM (Protected Virtual Machine) refers to the secure, isolated virtual machine environment supported by the Gunyah hypervisor. PVMFW (pVM Firmware) is the specific binary code (pvmfw.bin) executed first within a pVM to bootstrap secure boot, validate the environment, and derive unique secrets for that specific guest. In short, pVM is the container, while…

CVE-2026-20674: Sensitive information could potentially be accessed through Accessibility services while the device is locked. This issue is fixed in iOS 26.3 and iPadOS 26.3. (3rd Mar 2026)
Preface: In iOS development, CVE-2026-20674 relates to a security vulnerability where sensitive information could potentially be accessed through Accessibility services while the device is locked. Background: UIApplication.shared.isProtectedDataAvailable impacts the iOS lockscreen because it directly reflects whether user-encrypted data (Keychain, files) is accessible based on the device’s lock status. When locked, this returns false, causing apps…
