Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-992786)
medium Nessus Plugin ID 281363
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-2025-992786 advisory.In the Linux kernel, the following vulnerability has been resolved:
stmmac: intel: Add a missing clk_disable_unprepare() call in intel_eth_pci_remove()
Commit 09f012e64e4b (stmmac: intel: Fix clock handling on error and remove paths) removed this clk_disable_unprepare()
This was partly revert by commit ac322f86b56c (net: stmmac: Fix clock handling on remove path) which removed this clk_disable_unprepare() because:
While unloading the dwmac-intel driver, clk_disable_unprepare() is being called twice in stmmac_dvr_remove() and intel_eth_pci_remove(). This causes kernel panic on the second call.
However later on, commit 5ec55823438e8 (net: stmmac: add clocks management for gmac driver) has updated stmmac_dvr_remove() which do not call clk_disable_unprepare() anymore.
So this call should now be called from intel_eth_pci_remove().
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.
