Vyper from 0.1.0b4 before 0.3.0 contains a memory corruption vulnerability caused by an incorrect stack tip pointer when internal function calls are performed inside arrays. Contracts placing internal calls in nested array elements, external call arguments, struct literals, or raw_log topics can have memory corrupted, producing incorrect contract behavior.

CVE-2021-480187.4 ALT—
———Vyper from 0.2.13 before 0.2.15 allocates storage slots for @nonreentrant reentrancy locks at the same locations as contract storage variables. When a function using @nonreentrant is called, setting the lock overwrites the overlapping storage variable, corrupting contract state and breaking the contract's intended logic.6hCVE-2020-372866.5 MED—
———Vyper from 0.1.0b4 before 0.3.0 contains a memory corruption vulnerability caused by an incorrect stack tip pointer when internal function calls appear inside tuples or nested calls. Contracts using such calls as tuple elements, call arguments, or builtin arguments like concat or ecrecover can return corrupted values or pass wrong arguments to external calls.6hCVE-2026-1133009.6 CRÍ—
———Out of bounds write in Forms in Google Chrome prior to 156.0.8078.47 allowed a remote attacker to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Low)6hCVE-2026-1095765.5 MED—
———The parser in PEAK-System PCAN driver correctly detected the malformed record, but the loop iterating the record list advanced its processed-bytes counter even when a record had been rejected as invalid.10hCVE-2026-1001348.8 ALT—
———Acrobat for Edge is affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.11hCVE-2026-95109——
———The Cortex-A7 MMU Modules port validates a caller-supplied buffer by translating **one address** — the first byte. The common Module Manager hands its range check the module instance, the start address and the complete byte size; the Cortex-A7 implementation discarded the instance and the size and asked the MMU a single question about the start.
A memory-protected module therefore passed any range whose first byte was user-readable, however far the rest of it reached. Privileged dispatch code then read or wrote the whole range. Because every protected-module dispatcher that consumes a buffer or an extra-parameter array goes through this one macro, the defect is not in any individual service: it is in the primitive all of them rely on.11h
