In the Linux kernel, the following vulnerability has been resolved: ice: fix PTP cleanup on driver removal in error path Improve the cleanup on releasing PTP resources in error path. The error case might happen either at the driver probe and PTP feature initialization or on PTP restart (errors in reset handling, NVM update etc). In both cases, calls to PF PTP cleanup (ice_ptp_cleanup_pf function) and 'ps_lock' mutex deinitialization were missed. Additionally, ptp clock was not unregistered in the latter case. Keep PTP state as 'uninitialized' on init to distinguish between error scenarios and to avoid resource release duplication at driver removal. The consequence of missing ice_ptp_cleanup_pf call is the following call trace dumped when ice_adapter object is freed (port list is not empty, as it is required at this stage): [ T93022] ------------[ cut here ]------------ [ T93022] WARNING: CPU: 10 PID: 93022 at ice/ice_adapter.c:67 ice_adapter_put+0xef/0x100 [ice] ...

AI Analysis
Technical Summary
The Linux kernel ice driver had a flaw in handling cleanup of PTP resources on error paths, specifically missing calls to ice_ptp_cleanup_pf and mutex deinitialization, and failing to unregister the ptp clock during certain error scenarios. This caused kernel warnings and potential resource leaks when the ice_adapter object was freed. The fix improves cleanup procedures by ensuring PTP state is set to 'uninitialized' on init and properly releasing resources during driver removal and error handling.
Potential Impact
The vulnerability can cause kernel warnings and improper resource cleanup, potentially leading to system instability or denial of service conditions. The CVSS vector indicates high impact on confidentiality, integrity, and availability, but no known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since this is a Linux kernel driver issue, monitor official Linux kernel releases and update to a fixed kernel version once available. No specific workaround is provided in the data.
