CVE-2026-34183

A flaw was found in OpenSSL's QUIC PATHCHALLENGE handler. A remote attacker can exploit this vulnerability by flooding a QUIC client or server with specially crafted PATHCHALLENGE frames. This leads to unbounded memory allocation within the local QUIC stack, as the system continuously allocates...

CVE-2026-52759 Ghidra < 12.1.1 - Denial of Service via Uncontrolled Memory Allocation in Mach-O Parser

Ghidra before 12.1.1 contains an uncontrolled memory allocation vulnerability in the Mach-O binary parser that allows attackers to cause denial of service. An attacker can supply a crafted Mach-O binary with an arbitrarily large ncmds load command count value, forcing the parser to allocate...
