CVE-2026-88708 · Severity: info · Published 2026-11-10

An off-by-one error in ASUS Router firmware allows an unauthenticated attacker within network proximity to send a specially crafted packet that overwrites memory and crashes the router's service. This could lead to temporary unavailability of the router and loss of network connectivity for devices depending on it.

## Technical details

An off-by-one error in packet header processing allows an unauthenticated nearby attacker to trigger memory corruption by sending a packet with a specific header length. The vulnerability can cause the affected service to crash due to memory overwrite, requiring a restart. An adjacent attack vector is required, meaning the attacker must be on the local network or within wireless range.
