Vyper input validation error vulnerability

A input validation error vulnerability exists in VyperLang Vyper versions 0.4.0b1 through 0.5.0b1. This vulnerability arises because parseName parses the names of constants and default parameters from imported modules at the function call site rather than at their declaration site. When contract...

CVE-2026-64174 wifi: cfg80211: advance loop vars in cfg80211_merge_profile()

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: advance loop vars in cfg80211mergeprofile cfg80211mergeprofile reassembles a Multi-BSSID non-transmitted BSS profile that has been split across multiple consecutive MBSSID elements. Its while-loop calls...

EUVD-2026-20004

Arithmetic over induction variables in loops were not correctly checked for underflow or overflow. As a result, the compiler would allow for invalid indexing to occur at runtime, potentially leading to memory corruption...

Vyper vulnerable to integer overflow in loop

Impact Due to missing overflow check for loop variables, by assigning the iterator of a loop to a variable, it is possible to overflow the type of the latter. In the following example, calling test returns 354, meaning that the variable a did store 354 a value out of bound for the type uint8. Vyp...
