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

  - Issue summary: The DTLS retransmission logic does not correctly handle a handshake message write that is     suspended part-way through. The retransmitted message can be read past the message buffer and the     retransmission overwrites the internal state the suspended write needs to resume correctly. Impact     summary: The retransmitted message can disclose a heap memory to the peer as plaintext handshake data or     cause a crash and a Denial of Service when the read reaches an unmapped memory region. CWE: CWE-125: Out-     of-bounds Read Description: DTLS handshake messages can be written out in multiple fragments, and a write     can suspend mid-message (returning WANT_WRITE) if the underlying transport temporarily cannot accept more     data. While such a write is suspended, the DTLS retransmission timer may independently fire and ask the     retransmission logic to resend an earlier, already-acknowledged-as-sent message from its retransmit queue.
    The retransmission logic reused the same internal buffer and position tracking as the message that was     still being written, without resetting the position back to the start of the message being retransmitted.
    As a result the retransmission was read starting from wherever the suspended write had left off, producing     a mislabelled message whose body was leftover bytes from the other, larger message still in flight -     content that was never meant to be sent at that point, and which could run past the end of the allocated     buffer. Separately, even when the retransmission is positioned correctly, allowing it to run to completion     while another write is suspended overwrites the same shared bookkeeping that the suspended write depends     on to resume. When the application later resumes the suspended write (via a subsequent SSL_read(),     SSL_write(), SSL_accept(), or SSL_connect() call), it finds that bookkeeping in a state inconsistent with     the message and aborts the process in a debugging build. The fix resets the retransmission's read position     to the start of the message before resending, and skips retransmission entirely whenever a handshake write     is still suspended, deferring to the next call that resumes it instead. FIPS impact: no The affected code     is outside the FIPS module boundary. (CVE-2026-84782)
