The CentOS Linux 8.5 host has packages installed that are affected by a vulnerability as referenced in the TuxCare CENTOS8.5:CLSA-2026:1779180310 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: ptrace: slightly saner     'get_dumpable()' logic The 'dumpability' of a task is fundamentally about the memory image of the task -     the concept comes from whether it can core dump or not - and makes no sense when you don't have an     associated mm. And almost all users do in fact use it only for the case where the task has a mm pointer.
    But we have one odd special case: ptrace_may_access() uses 'dumpable' to check various other things     entirely independently of the MM (typically explicitly using flags like PTRACE_MODE_READ_FSCREDS).
    Including for threads that no longer have a VM (and maybe never did, like most kernel threads). It's not     what this flag was designed for, but it is what it is. The ptrace code does check that the uid/gid     matches, so you do have to be uid-0 to see kernel thread details, but this means that the traditional     drop capabilities model doesn't make any difference for this all. Make it all make a *bit* more sense by     saying that if you don't have a MM pointer, we'll use a cached last dumpability flag if the thread ever     had a MM (it will be zero for kernel threads since it is never set), and require a proper CAP_SYS_PTRACE     capability to override. (CVE-2026-46333)

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