Overview

CVE-2026-68133 is a known-severity vulnerability. It was published on August 10, 2026.

Technical description

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

ice: fix PTP Call Trace during PTP release

If a PF reset occurs when the PTP state is ICE_PTP_UNINIT, then

ice_ptp_rebuild() will update the state to ICE_PTP_ERROR. This will

result in the following PTP release call trace during driver unload:

kernel BUG at lib/list_debug.c:52!

ice_ptp_release+0x332/0x3c0 [ice]

ice_deinit_features.part.0+0x10e/0x120 [ice]

ice_remove+0x100/0x220 [ice]

This was observed when passing PF1 through to a VM. ice_ptp_init()

fails because ctrl_pf is NULL and sets the state to ICE_PTP_UNINIT.

Fix by detecting the ICE_PTP_UNINIT state in ice_ptp_rebuild() and

returning without error, preventing the invalid state transition to

ICE_PTP_ERROR. The only valid path to ICE_PTP_ERROR is from

ICE_PTP_RESETTING after a failed rebuild.

How can CyberStrike help with CVE-2026-68133?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-68133 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
