In the Linux kernel, the following vulnerability has been resolved: s390/bpf: Zero-extend bpf prog return values and kfunc arguments s390x ABI requires callers to zero-extend unsigned arguments and sign-extend signed arguments, and callees to zero-extend unsigned return values and sign-extend signed return values. s390 BPF JIT currently implements only sign extension. Fix this omission and implement zero extension too.

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

  - s390/bpf: Zero-extend bpf prog return values and kfunc arguments s390x ABI requires callers to zero-extend     unsigned arguments and sign-extend signed arguments, and callees to zero-extend unsigned return values and     sign-extend signed return values. s390 BPF JIT currently implements only sign extension. Fix this omission     and implement zero extension too. (CVE-2026-53110)

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