CVE-2026-56786

RTKLIB 2.4.3 contains an out-of-bounds write in decode_type1033 that fails to clamp length counters to the destination buffer. This allows up to a 191-byte overflow into fixed 64-byte descriptor fields when processing a crafted RTCM3 type-1033 message. An attacker controlling an NTRIP or serial R...

CVE-2026-56770 libais 0.15 - Out-of-bounds Vector Access in VdmStream::AddLine via Invalid Sequential Message ID

libais through 0.15 VdmStream::AddLine uses an unchecked sentinel value as a vector index when processing AIS sentences with empty or out-of-range sequential message IDs. Remote attackers can crash services or vessel systems by sending crafted AIVDM sentences over VHF marine radio or IP feeds,...

net/textproto: golang: Golang net/textproto: Misleading error messages via input injection

A flaw was found in the net/textproto package in Golang. When functions in this package return errors, they include their input as part of the error message. An attacker could exploit this by injecting misleading content into these error messages, which are then printed or logged. This could lead...
