Description
This security bulletin contains information about 2 vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2026-44250)
CWE-ID: CWE-400 - Resource exhaustion
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 uncontrolled resource consumption in RedisArrayAggregator when processing deeply nested Redis array headers. A remote attacker can send a specially crafted Redis payload to cause a denial of service.
The issue can lead to memory exhaustion and an OutOfMemoryError in applications that handle untrusted Redis traffic.
2) Resource exhaustion (CVE-ID: CVE-2026-44890)
CWE-ID: CWE-400 - Resource exhaustion
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 uncontrolled resource consumption in RedisDecoder when processing crafted Redis payloads that omit the required \r\n terminator. A remote attacker can send specially crafted Redis payloads across multiple concurrent connections to cause a denial of service.
Exploitation requires multiple concurrent connections to exhaust the direct memory pool and trigger an OutOfDirectMemoryError.
