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

  - OpenSC before 0.27.0, fixed in commit 0358817, contains a stack and heap buffer overrun vulnerability in     the do_key_value() function in src/pkcs15init/profile.c that allows attackers to corrupt memory by     supplying a crafted profile configuration file. During pkcs15-init invocation, a key value entry beginning     with '=' followed by more than sizeof(keybuf) characters is copied into keybuf via memcpy without a length     check, causing both stack and heap buffer overruns. (CVE-2026-40528)

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

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:2697-1 advisory.

    This update for opensc fixes the following issues

    - CVE-2025-49010: stack-buffer-overflow via crafted smart card or USB device responses (bsc#1261214).
    - CVE-2025-66037: crafted input can cause an out-of-bounds read (bsc#1261218).
    - CVE-2025-66038: improper compact-TLV length validation can lead to crash or unexpected behavior     (bsc#1261219).
    - CVE-2025-66215: crafted smart card or USB device can cause a stack-buffer-overflow write (bsc#1261220).
    - CVE-2026-10275: global buffer overflow during key pair generation tests due to missing input validation     (bsc#1267246).
    - CVE-2026-40528: stack and heap buffer overrun in the `do_key_value()` function due to missing length     check allows for       memory corruption via a crafted profile configuration file (bsc#1266963).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:2657-1 advisory.
