    Hi,

    The following vulnerability was published for suricata.

    CVE-2025-53538[0]:
    | Suricata is a network IDS, IPS and NSM engine developed by the OISF
    | (Open Information Security Foundation) and the Suricata community.
    | In versions 7.0.10 and below and 8.0.0-beta1 through 8.0.0-rc1,
    | mishandling of data on HTTP2 stream 0 can lead to uncontrolled
    | memory usage, leading to loss of visibility. Workarounds include
    | disabling the HTTP/2 parser, and using a signature like drop http2
    | any any -> any any (frame:http2.hdr; byte_test:1,=,0,3;
    | byte_test:4,=,0,5; sid: 1;) where the first byte test tests the
    | HTTP2 frame type DATA and the second tests the stream id 0. This is
    | fixed in versions 7.0.11 and 8.0.0.


    If you fix the vulnerability please also make sure to include the
    CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
