CVE-2026-77014 Libsoup: libsoup: integer truncation in sort_ranges() comparator causes silent omission of http range responses

A flaw was found in libsoup's SoupServer HTTP Range header processing. The sortranges comparator in soup-message-headers.c truncates a 64-bit subtraction result to 32-bit int, flipping the sign for range offsets differing by more than INTMAX. This causes silent omission of requested byte ranges...
