CVE-2026-114045

A flaw was found in FreeRDP. An integer wraparound in rdpsndserverselectformat DVIADPCM block-alignment arithmetic bypasses validation in the server-side rdpsnd channel. A malicious RDP client can send crafted SNDCFORMATS PDUs, causing an unbounded heap write during server audio playback that may...

DEBIAN-CVE-2026-114045

FreeRDP before 3.32.1 contains a heap-based buffer overflow in the server-side rdpsnd channel because an integer wraparound in rdpsndserverselectformat DVIADPCM block-alignment arithmetic bypasses validation. A malicious RDP client can send two SNDCFORMATS PDUs with an nBlockAlign too small for...

CVE-2026-114118

Vyper versions 0.3.4 through 0.5.0b1 are vulnerable to an offset validation bypass in the create_from_blueprint function. The root cause is a uint256 subtraction performed without verifying that the code_offset is within the blueprint's code size, allowing a large offset to wrap around to a small...

CVE-2026-114118 Vyper 0.3.4 through 0.5.0b1 create_from_blueprint Offset Validation Bypass via Unsigned Wraparound

Vyper 0.3.4 through 0.5.0b1 computes the remaining blueprint size in createfromblueprint by uint256 subtraction without first checking that codeoffset is below the blueprint's code size, so a huge offset wraps to a small positive value. An attacker controlling codeoffset can make a factory deploy...
