Security updates and other improvements

Important: This release addresses a critical security vulnerability in the interface handling trace requests. The identified issue involves memory corruption, which could potentially be exploited to cause denial of service (DoS) conditions. Note that this issue is related to the internal tracing interface and NOT Traces telemetry data handling. It is highly recommended to update to this version immediately to ensure the stability and security of your system.

    • kernel: fix incorrect assignment of Linux Kernel version between major and minor (#8797)
    • http_server: fix keep-alive for HTTP/1.1 requests
    • config: fix error message grammar (#8818)
