CVE-2026-52937

CVE-2026-52937 details a stack information leak in the Linux kernel related to the macvtap mac address path. In tap_ioctl() for SIOCGIFHWADDR, the code copies 16 bytes from an uninitialized on-stack sockaddr_storage to userspace via ifr_hwaddr. The implementation only writes sa_family and dev-&gt...

Siemens RUGGEDCOM RST2428P Improper Input Validation (CVE-2026-23236)

In the Linux kernel, the following vulnerability has been resolved: fbdev: smscufx: properly copy ioctl memory to kernelspace The UFXIOCTLREPORTDAMAGE ioctl does not properly copy data from userspace to kernelspace, and instead directly references the memory, which can cause problems if invalid...

CVE-2026-8049 CVE-2026-8049

In SignalRGB versions prior to 1.3.7.0, the \.\SignalIo device object is created without an explicit SDDL security descriptor and without FILEDEVICESECUREOPEN. This results in overly permissive default access control, allowing any authenticated local user to obtain a handle to the device and issu...
