CVE-2026-40612 jq: Stack overflow via unbounded recursion in jv_contains

jq is a command-line JSON processor. In 1.8.1 and earlier, jvcontains recurses into nested arrays/objects with no depth limit. With a sufficiently nested input structure built programmatically with reduce, since the JSON parser caps at depth 10000, the C stack is exhausted...

CVE-2026-40612

CVE-2026-40612 affects jq (1.8.1 and earlier). The root cause is an unbounded recursion in the function jv_contains that recurses into nested arrays/objects with no depth limit, eventually exhausting the C stack when presented with a deeply nested input (constructed programmatically with reduce, ...

CVE-2026-41257

The CVE concerns jq (1.8.1 and earlier) where the bytecode VM’s data stack uses a signed int to track allocation size. When the stack grows beyond ~1 GiB (e.g., via deeply nested generator forks), the doubling arithmetic overflows, causing the wrapped value to be passed to realloc and then used f...

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 ...
