Linux Distros Unpatched Vulnerability : CVE-2026-5441

critical Nessus Plugin ID 305814

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.

- An out-of-bounds read vulnerability exists in the `DecodePsmctRle1` function of `DicomImageDecoder.cpp`.
The `PMSCT_RLE1` decompression routine, which decodes the proprietary Philips Compression format, does not properly validate escape markers placed near the end of the compressed data stream. A crafted sequence at the end of the buffer can cause the decoder to read beyond the allocated memory region and leak heap data into the rendered image output. (CVE-2026-5441)

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

Solution

There is no known solution at this time.
