In languages without memory safety, such as C and C++, type confusion can lead to out-of-bounds memory access.\nWhile this weakness is frequently associated with unions when parsing data with many different embedded object types in C, it can be present in any application that can interpret the same variable or memory location in multiple ways.\nThis weakness is not unique to C and C++. For example, errors in PHP applications can be triggered by providing array parameters when scalars are expected, or vice versa. Languages such as Perl, which perform automatic conversion of a variable of one type when it is accessed as if it were another type, can also contain these issues.","Incomplete","Base",2,false,[],{"title":82,"metaDescription":83,"keywords":84,"canonicalUrl":85,"structuredData":86},"What is CVE-2021-26635?
