Description

This security bulletin contains information about 1 vulnerability.


1) Improper Resource Shutdown or Release (CVE-ID: CVE-2026-48006)

CWE-ID: CWE-404 - Improper Resource Shutdown or Release

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper resource shutdown or release in RedisArrayAggregator when a Redis pipeline connection closes before a RESP array aggregate completes. A remote attacker can repeatedly open and close connections to cause a denial of service.

The issue leaks pooled direct-memory buffers retained in per-handler state, which can exhaust the shared direct-memory pool and trigger allocation failures across Netty channels in the same process.
