Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-380009)

medium Nessus Plugin ID 267380

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-380009 advisory.

 In the Linux kernel, the following vulnerability has been resolved:

 clk: Fix clk_core_get NULL dereference

 It is possible for clk_core_get to dereference a NULL in the following sequence:

 clk_core_get() of_clk_get_hw_from_clkspec()
 __of_clk_get_hw_from_provider()
 __clk_get_hw()

 __clk_get_hw() can return NULL which is dereferenced by clk_core_get() at hw->core.

 Prior to commit dde4eff47c82 (clk: Look for parents with clkdev based clk_lookups) the check IS_ERR_OR_NULL() was performed which would have caught the NULL.

 Reading the description of this function it talks about returning NULL but that cannot be so at the moment.

 Update the function to check for hw before dereferencing it and return NULL if hw is NULL.

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.
