CVE-2026-20446

In sec boot, there is a possible out of bounds write due to an integer overflow. This could lead to local denial of service, if an attacker has physical access to the device, with User execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS09963054; Issue ID:...

EUVD-2025-209287

The Semtech LR11xx LoRa transceivers implement secure boot functionality using digital signatures to authenticate firmware. However, the implementation uses a non-standard cryptographic hashing algorithm that is vulnerable to second preimage attacks. An attacker with physical access to the device...

EUVD-2025-209282

An improper access control vulnerability exists in Semtech LoRa LR11xxx transceivers running early versions of firmware where the memory write command accessible via the physical SPI interface fails to enforce write protection on the program call stack. An attacker with physical access to the SPI...
