Linux Distros Unpatched Vulnerability : CVE-2026-9669

high Nessus Plugin ID 320094

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.

- bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to resume from an invalid internal state and perform out-of-bounds writes to a stack buffer. This could crash the process when processing untrusted data. (CVE-2026-9669)

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

Solution

There is no known solution at this time.
