{"id":"RLSA-2026:98496","summary":"Important: jq security update","details":"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.\n\nSecurity Fix(es):\n\n* jq: out-of-bounds read in jv_parse_sized() on error formatting for non-NUL-terminated buffers (CVE-2026-39979)\n\n* jq: jq: Denial of Service via crafted JSON object causing hash collisions (CVE-2026-40164)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.","modified":"2026-11-13T12:45:06.807665291Z","published":"2026-11-13T12:04:47.873079Z","upstream":["CVE-2026-39979","CVE-2026-40164"],"database_specific":{"license":"CC-BY-4.0","license_url":"https://creativecommons.org/licenses/by/4.0/","source_advisory":"RHSA-2026:98496"},"references":[{"type":"ADVISORY","url":"https://errata.rockylinux.org/RLSA-2026:98496"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2458077"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2458084"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:98496"}],"affected":[{"package":{"name":"jq","ecosystem":"Rocky
