In the Linux kernel, the following vulnerability has been resolved: net: dsa: b53: do not enable EEE on bcm63xx BCM63xx internal switches do not support EEE, but provide multiple RGMII ports where external PHYs may be connected. If one of these PHYs are EEE capable, we may try to enable EEE for the MACs, which then hangs the system on access of the (non-existent) EEE registers. Fix this by checking if the switch actually supports EEE before attempting to configure it.

Are you affected?

Enter the version you run. The result uses only the ranges stored on this record.

The check returns affected, not affected, or incomplete. It does not guess a version that is missing from the record.

How to fix CVE-2025-38272

What to do

Three questions, each answered from this record only. Confirm the vendor advisory before you patch.

Should you patch?

No confirmed exploitation is on record for CVE-2025-38272. EPSS is 0.19%. Act only if a listed version of linux kernel is installed.

Which versions are affected?

Compare what you have installed with linux/linux kernel < 6.12.46; linux/linux kernel < 6.15.3; Linux Linux 22256b0afb12333571ad11799fa68fd27e4f4e80 <2dbccf1eb8c04b84ee3afdb1d6b787db02e7befc 22256b0afb12333571ad11799fa68fd27e4f4e80 <2dbccf1eb8c04b84ee3afdb1d6b787db02e7befc. Compare the installed version with the linked vendor advisory before you change production.

What should an analyst verify?

No weakness class is stored. EPSS 0.19%. There is no CISA KEV listing. No Exploit-DB or Metasploit reference is linked. Use the source links for the original advisory.
