GHSA-3VCG-J39X-CWFM Vyper's `slice()` may elide side-effects when output length is 0

Impact the slice builtin can elide side effects when the output length is 0, and the source bytestring is a builtin msg.data or .code. the reason is that for these source locations, the check that length = 1 is skipped:...

Insufficient Control Flow Management

Overview vyper is a Pythonic Smart Contract Language for the EVM. Affected versions of this package are vulnerable to Insufficient Control Flow Management through optimization in the concat function. An attacker can skip evaluation of side effects when the length of an argument provided to the...

GHSA-QHR6-MGQR-MCHM Vyper's `concat()` builtin may elide side-effects for zero-length arguments

Impact concat may skip evaluation of side effects when the length of an argument is zero. this is due to a fastpath in the implementation which skips evaluation of argument expressions when their length is zero:...

CVE-2025-47285

Vyper is the Pythonic Programming Language for the Ethereum Virtual Machine. In versions up to and including 0.4.2rc1, concat may skip evaluation of side effects when the length of an argument is zero. This is due to a fastpath in the implementation which skips evaluation of argument expressions...

CVE-2025-47774

CVE-2025-47774 relates to Vyper (Pythonic language for the EVM). The issue affects Vyper versions up to and including 0.4.2rc1 where slice() can elide side effects when length is 0 for certain source bytestrings (e.g., msg.data or .code). The root cause is that the length >= 1 check is skipped...

CVE-2025-47285

CVE-2025-47285 affects Vyper up to and including 0.4.2rc1, where the built-in concat() may skip evaluation of side effects when an argument has zero length due to a fastpath in the implementation. The issue arises because argument expressions with zero length may bypass evaluation, which could su...

PT-2025-21348

Name of the Vulnerable Software and Affected Versions: Vyper versions up to and including 0.4.2rc1 Description: The issue concerns the slice builtin in Vyper, which can elide side effects when the output length is 0 and the source bytestring is a builtin, such as msg.data or .code. This occurs...

kernel: Kernel: Denial of Service in pci_endpoint_test due to zero-length DMA mapping

A flaw was found in the Linux kernel's pciendpointtest module. A local attacker with low privileges could exploit this vulnerability by providing a zero-length Direct Memory Access DMA mapping to the dmamapsingle function. This improper input validation can lead to a kernel panic, resulting in a...
