CVE-2025-59148
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Versions 8.0.0 and below incorrectly handle the entropy keyword when not anchored to a "sticky" buffer, which can lead to a segmentation fault. This issue is fixed in version 8.0.1. To workaround this issue, users can disable rules using the entropy keyword, or validate they are anchored to a sticky buffer.
