The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-004001 advisory.

    A use after free in the Linux kernel infiniband hfi1 driver in versions prior to 5.10-rc6 was found in the     way user calls Ioctl after open dev file and fork. A local user could use this flaw to crash the system.

Tenable has extracted the preceding description block directly from the Unity Linux 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 SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2021-3347: A use-after-free was discovered in the PI futexes during fault handling, allowing local users to execute code in the kernel (bnc#1181349).

CVE-2021-3348: Fixed a use-after-free in nbd_add_socket that could be triggered by local attackers (with access to the nbd device) via an I/O request at a certain point during device setup (bnc#1181504).

CVE-2021-20177: Fixed a kernel panic related to iptables string matching rules. A privileged user could insert a rule which could lead to denial of service (bnc#1180765).

(bnc#1180812)

CVE-2020-27835: A use-after-free in the infiniband hfi1 driver was found, specifically in the way user calls Ioctl after open dev file and fork. A local user could use this flaw to crash the system (bnc#1179878).
