RIOT OS versions up to and including 2026.01-devel-317 contain a stack-based buffer overflow vulnerability in the tapslip6 utility. The vulnerability is caused by unsafe string concatenation in the devopen() function, which constructs a device path using unbounded user-controlled input. The utility uses strcpy() and strcat() to concatenate the fixed prefix '/dev/' with a user-supplied device name provided via the -s command-line option without bounds checking. This allows an attacker to supply an excessively long device name and overflow a fixed-size stack buffer, leading to process crashes and memory corruption.

DLL hijacking vulnerability in Evope Collector 1.1.6.9.0 and related components load the wtsapi32.dll library from an uncontrolled search path (C:\ProgramData\Evope). This allows local unprivileged attackers to execute arbitrary code or escalate privileges to SYSTEM by placing a crafted DLL in that location. The vulnerable component is Evope.Service.exe, which runs with SYSTEM privileges and automatically loads the DLL on startup or reboot.

An issue in Evope Core v.1.1.3.20 allows a local attacker to obtain sensitive information via the use of hard coded cryptographic keys.
