CVE-2024-32761Network attack vector

Information disclosure and TMM restart via memory leak

Published May 8, 2024 · Updated Feb 3, 2026

Memory buffer bounds errors in F5 BIG-IP tenants before 15.1.10 disclose random memory data and can restart a TMM. BIG-IP tenant TMMs on VELOS and rSeries can emit up to 64 bytes of non-contiguous randomized memory, with rare occurrences restarting the TMM. The event occurs randomly under unspecified conditions and cannot be deliberately triggered, limiting the impact to incidental disclosure and rare service interruption.
