RLSA-2026:19151

jq is a lightweight and flexible command-line JSON processor. jq is like sed for JSON data. You can use it to slice, filter, map, or transform structured data with the same ease that sed, awk, grep, or similar applications allow you to manipulate text.

Security Fix(es):

• jq: out-of-bounds read in jvparsesized() on error formatting for non-NUL-terminated buffers (CVE-2026-39979)

• jq: jq: Denial of Service via crafted JSON object causing hash collisions (CVE-2026-40164)
