CVE-2026-41257 jq: Signed-int overflow in `stack_reallocate` (jq VM stack)

jq is a command-line JSON processor. In 1.8.1 and earlier, the jq bytecode VM's data stack tracks its allocation size in a signed int. When the stack grows beyond ≈1 GiB via deeply nested generator forks, the doubling arithmetic overflows. The wrapped value is passed to realloc and then used for ...
