CVE-2024-38536

CVSS v2.0

7.8

High

VectorAV:N/AC:L/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions: Suricata versions prior to 7.0.6
Description: A memory allocation failure due to http.memcap being reached leads to a NULL-ptr reference, resulting in a crash. This issue can be exploited by a remote attacker to cause a denial of service.
Recommendations: For versions prior to 7.0.6, upgrade to 7.0.6 to resolve the issue. As a temporary workaround, consider adjusting the http.memcap setting to prevent the memory allocation failure until a patch is applied. Restrict access to the Suricata engine to minimize the risk of exploitation.
