EUVD-2026-33449

The SocketCAN implementation validates the length of a user-provided buffer containing a socketcanframe object using only a NETASSERT statement in zcansendtoctx before dereferencing it in socketcantocanframe. In production builds where assertions are disabled, a userspace application that control...

CVE-2026-5071

CVE-2026-5071 affects Zephyr RTOS SocketCAN. A NET_ASSERT-based length check in zcan_sendto_ctx() allows out-of-bounds reads in socketcan_to_can_frame() when an attacker controls the length passed to a sendto syscall and assertions are disabled in production builds. Consequences include denial-of...

CVE-2026-44518 liboqs: XMSS Buffer Overread Bug

liboqs is a C-language cryptographic library that provides implementations of post-quantum cryptography algorithms. Prior to 0.16.0, an out-of-bounds read has been identified in the XMSS and XMSS^MT stateful signature verification code. When the verification function is called with a signature...

CVE-2026-44518

liboqs (C library for post-quantum crypto) exposes a buffer overread in XMSS/XMSS^MT stateful signature verification prior to 0.16.0. If verify is called with a signature shorter than the parameter’s sig_bytes, length isn't validated and the code reads past the end of the signature buffer. The ex...
