24 Jun 2025 — NeKernal is a free and open-source operating system stack. Prior to version 0.0.3, there are several memory safety issues that can lead to memory corruption, disk image corruption, denial of service, and potential code execution. These issues stem from unchecked memory operations, unsafe typecasting, and improper input validation. This issue has been patched in version 0.0.3. • https://github.com/nekernel-org/nekernel/commit/6506875ad0ab210b82a5c4ce227bf851508de17d • CWE-20: Improper Input Validation CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 9.8EPSS: 0%CPEs: 1EXPL: 0CVE-2025-48990 – NeKernel has Heap Overflow in `rt_copy_memory`

02 Jun 2025 — NeKernal is a free and open-source operating system stack. Version 0.0.2 has a 1-byte heap overflow in `rt_copy_memory`, which unconditionally wrote a null terminator at `dst[len]`. When `len` equals the size of the destination buffer (256 bytes), that extra `'\0'` write overruns the buffer by one byte. To avoid breaking existing callers or changing the public API, the patch in commit fb7b7f658327f659c6a6da1af151cb389c2ca4ee takes a minimal approach: it simply removes the overflow-causing line without addin... • https://github.com/nekernel-org/nekernel/commit/fb7b7f658327f659c6a6da1af151cb389c2ca4ee • CWE-122: Heap-based Buffer Overflow •
