CVE-2025-55094 Details
Description
In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _nx_icmpv6_validate_options() when handling a packet with ICMP6 options.
A moderate out-of-bounds read vulnerability has been identified in Eclipse NetX Duo versions through 6.4.3. The issue arises in the networking support module for Eclipse Foundation ThreadX, specifically within the `_nx_icmpv6_validate_options()` function. This function, responsible for parsing and validating ICMPv6 options in received packets, can be exploited by malformed ICMPv6 packets that contain incomplete option structures. Such packets may cause the function to read memory outside the intended bounds, leading to potential information disclosure or memory corruption.
Users can upgrade to Eclipse NetX Duo version 6.4.4 or later to address this vulnerability.
