Ubuntu Security Advisories
3 days 15 hours ago
It was discovered that AOM incorrectly handled the first-pass statistics buffer in Look-Ahead Processing (LAP) mode. An attacker could possibly use this issue to cause a heap buffer overflow, leading to a denial of service or possibly execute arbitrary code. (CVE-2026-56208) It was discovered that AOM incorrectly validated spatial and temporal layer IDs in the SVC (Scalable Video Coding) encoder controls. An attacker could possibly use this issue to write to an arbitrary memory address, read out-of-bounds heap memory, or execute arbitrary code. (CVE-2026-56209, CVE-2026-56210, CVE-2026-56211)

Ubuntu Security Advisories
3 days 20 hours ago
Madelyn Olson discovered that Valkey incorrectly handled TLS connections under certain conditions. A remote attacker could possibly use this issue to cause Valkey to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-56684) It was discovered that Valkey incorrectly handled certain stream RDB payloads when executing the RESTORE command. An authenticated remote attacker could possibly use this issue to cause Valkey to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-63639) It was discovered that Valkey incorrectly handled cluster slot migration operations. A remote attacker could possibly use this issue to cause Valkey to crash, resulting in a denial of service. This issue was only addressed in Ubuntu 26.04 LTS. (CVE-2026-85522)
