The version of CBL-Mariner Releases installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2026-40164 advisory.

  - jq is a command-line JSON processor. Before commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784, jq used     MurmurHash3 with a hardcoded, publicly visible seed (0x432A9843) for all JSON object hash table     operations, which allowed an attacker to precompute key collisions offline. By supplying a crafted JSON     object (~100 KB) where all keys hashed to the same bucket, hash table lookups degraded from O(1) to O(n),     turning any jq expression into an O(n) operation and causing significant CPU exhaustion. This affected     common jq use cases such as CI/CD pipelines, web services, and data processing scripts, and was far more     practical to exploit than existing heap overflow issues since it required only a small payload. This issue     has been patched in commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784. (CVE-2026-40164)
