Linux Distros Unpatched Vulnerability : CVE-2026-8932

high Nessus Plugin ID 322442

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

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

- libcurl would reuse a previously created connection even when some mTLS config related option had been changed that should have prohibited reuse. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, some TLS settings related to client certificates were left out from the configuration match checks, making them match too easily. In particular options related to the private key. (CVE-2026-8932)

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

Solution

There is no known solution at this time.
