CVE-2021-31400 (GCVE-0-2021-31400)

Vulnerability from cvelistv5 – Published: 2021-08-19 10:52 – Updated: 2024-08-03 22:55

Summary

An issue was discovered in tcp_pulloutofband() in tcp_in.c in HCC embedded InterNiche 4.0.1. The TCP out-of-band urgent-data processing function invokes a panic function if the pointer to the end of the out-of-band data points outside of the TCP segment's data. If the panic function hadn't a trap invocation removed, it will enter an infinite loop and therefore cause DoS (continuous loop or a device reset).

Severity

No CVSS data available.
