CVE-2026-6679: Out-of-bounds Write

A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer is authenticated. The buffer overflow was due to an integer truncation when computing the length of the ACK record-number list, causing an undersized buffer to be allocated and then overrun. This...

CVE-2026-56789: Heap-based Buffer Overflow

RTKLIB through 2.4.3 contains a heap buffer overflow vulnerability in the readrnxobsb function in src/rinex.c that allows attackers to trigger memory corruption by failing to clamp satellite count values from RINEX epoch headers. Attackers can craft malicious RINEX files declaring more than 64...

CVE-2026-49839: Out-of-bounds Write

jq is a command-line JSON processor. Prior to 1.8.2, jq --rawfile can turn a handled oversized-string error into invalid-state reuse and a real heap out-of-bounds write in assertion-disabled builds. When jvloadfileraw=1 reads an attacker-controlled file, it repeatedly appends file chunks to the...
