    A flaw has been found in Xen. An unprivileged guest can cause Denial of Service (DoS) of the host by
    sending network packets to the backend, causing the backend to crash. (CVE-2023-46838)

    In the Linux kernel, the following vulnerability has been resolved:

    EDAC/thunderx: Fix possible out-of-bounds string access

    Enabling -Wstringop-overflow globally exposes a warning for a common bugin the usage of strncat():

    drivers/edac/thunderx_edac.c: In function
    'thunderx_ocx_com_threaded_isr':drivers/edac/thunderx_edac.c:1136:17: error: 'strncat' specified bound
    1024 equals destination size [-Werror=stringop-overflow=]1136 |                 strncat(msg, other,
    OCX_MESSAGE_SIZE);|                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~...1145 |
    strncat(msg, other, OCX_MESSAGE_SIZE);...1150 |                                 strncat(msg, other,
    OCX_MESSAGE_SIZE);

    ...

    Apparently the author of this driver expected strncat() to behave theway that strlcat() does, which uses
    the size of the destination bufferas its third argument rather than the length of the source buffer.
    Theresult is that there is no check on the size of the allocated buffer.

    Change it to strlcat().
