CVE-2023-54056

The CVE-2023-54056 entry concerns the Linux kernel kheaders path. The underlying issue was that kernel_headers_data was defined as a char array, which trips FortifySource checks during memcpy by treating addresses as byte arrays; the fix is to define them as proper arrays (as with other code path...
