CVE-2026-23824 | Unauthenticated Denial-of-Service via Crafted Messages in a Network Protocol Handling Component

Vulnerabilities exist in a protocol-handling component of AOS-8 and AOS-10 Operating Systems. An unauthenticated attacker could exploit these vulnerabilities by sending specially crafted network messages to the affected service. Due to insufficient input validation, successful exploitation may terminate a critical system process, resulting in a denial-of-service condition.

7.5 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
