The remote openSUSE 16 host has packages installed that are affected by a vulnerability as referenced in the openSUSE- SU-2026:21820-1 advisory.

    This update for opensc fixes the following issue:

    - CVE-2026-40510: stack buffer overflow in `piv_process_history()` allows physically present attackers to     trigger memory       corruption by presenting a crafted PIV smart card or USB device (bsc#1266964).

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

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

The AlmaLinux 9.2 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1780711381 advisory.

  - OpenSC before 0.27.0-rc1, fixed in commit 3f24f0b, contains a stack buffer overflow vulnerability in     piv_process_history() in src/libopensc/card-piv.c that allows physically present attackers to trigger     memory corruption by presenting a crafted PIV smart card or USB device returning a URL field longer than     118 bytes in the Key History Object ASN.1 response. (CVE-2026-40510)

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

The AlmaLinux 9.6 host has a package installed that is affected by a vulnerability as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1781267272 advisory.

  - OpenSC before 0.27.0-rc1, fixed in commit 3f24f0b, contains a stack buffer overflow vulnerability in     piv_process_history() in src/libopensc/card-piv.c that allows physically present attackers to trigger     memory corruption by presenting a crafted PIV smart card or USB device returning a URL field longer than     118 bytes in the Key History Object ASN.1 response. (CVE-2026-40510)

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