CVE-2026-826808.8 ALT—
——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.4hCVE-2026-58106—2.7%
——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 6.28.2.3dCVE-2026-183935.4 MED16.8%
——5A flaw was found in FFmpeg. The tdsc_load_cursor() function writes beyond
the bounds of a heap-allocated buffer when processing crafted TDSC cursor
data. A remote attacker could exploit this by supplying a specially crafted
video file, potentially leading to a denial of service or arbitrary code
execution.3dCVE-2026-78011—24.6%
——7An integer underflow vulnerability in the WatchGuard Fireware OS iked process allows a remote unauthenticated attacker to create a Denial of Service (DoS) condition in VPN processing by sending specially crafted network traffic.3dCVE-2026-78010—25.2%
——8A stack-based buffer overflow vulnerability in the WatchGuard Fireware OS iked process iallows a remote unauthenticated attacker to create a Denial of Service (DoS) condition in VPN processing by sending specially crafted network traffic.3dCVE-2026-78008—23.2%
——7A buffer overflow vulnerability in the WatchGuard Fireware OS Management Web UI allows an authenticated administrator with network access to cause a denial of service (DoS) condition or potentially execute arbitrary code by sending specially crafted network traffic.2d
