Linux Distros Unpatched Vulnerability : CVE-2026-41035

high Nessus Plugin ID 306775

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.

 - In rsync 3.0.1 through 3.4.1, receive_xattr relies on an untrusted length value during a qsort call, leading to a receiver use-after-free. The victim must run rsync with -X (aka --xattrs). On Linux, many (but not all) common configurations are vulnerable. Non-Linux platforms are more widely vulnerable.
 (CVE-2026-41035)

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

Solution

There is no known solution at this time.
