jq: out-of-bounds read in jv_parse_sized() on error formatting for non-NUL-terminated buffers

A flaw was found in jq, a command line JSON processor, specifically in the libjq API. Parsing a malformed JSON input from a non-NUL-terminated buffer using the jvparsesized function can cause an out-of-bounds read, resulting in an application crash and a possible memory disclosure within the erro...

jq is a command-line JSON processor. In commits before 2f09060afab23fe9390cce7cb860b10416e1bf5f, the jvparsesized API in libjq accepts a counted buffer with an explicit length parameter, but its error-handling path formats the input buffer using %s in jvstringfmt, which reads until a NUL terminat...

CVE-2026-39979

CVE-2026-39979 affects jq’s libjq jv_parse_sized(): the error path formats input with %s, reading past the caller-provided length for non-NUL-terminated buffers. This can cause an out-of-bounds read in malformed input, potentially enabling memory disclosure or process termination. The issue is pa...
