——0A weakness has been identified in D-Link DSM-G600 1.01. This affects an unknown function of the file /load_file.cgi of the component Multipart Handler. Executing a manipulation can lead to out-of-bounds write. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks.4h CVE-2026-58106—

——1CVE-2025-40843 https://github.com/advisories/GHSA-5xf2-f6ch-6p8r was fixed by replacing unchecked strcpy() with a bounded safe_strcpy() helper. At ldlogger-tool-gcc.c:129 the destination passed to that helper is fullPath + 2, but the size passed down is the full PATH_MAX. safe_strcpy() is strncpy(), which NUL-pads the destination out to the whole n, so this site writes 4096 bytes into the 4094 that remain — a 2-byte stack overflow on every invocation, independent of the input path's length. This issue affects CodeChecker: through 6.28.2.3d CVE-2026-183935.4 MED
