Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Netty is a network application framework for development of protocol servers and clients. In netty-codec-     haproxy prior to versions 4.1.135.Final and 4.2.15.Final, when decoding a PP2_TYPE_SSL TLV,     HAProxyMessage.readNextTLV() first calls `header.retainedSlice(header.readerIndex(), length)` and only     then reads the 1-byte client field and 4-byte verify field. If the attacker sets the TLV length below 5,     the subsequent readByte/readInt throws IndexOutOfBoundsException. HAProxyMessageDecoder only catches     HAProxyProtocolException around this call, so the IOOBE propagates and the retained slice on the pooled     cumulation buffer is never released. Versions 4.1.135.Final and 4.2.15.Final patch the issue.
    (CVE-2026-44893)

Note that Nessus relies on the presence of the package as reported by the vendor.
