CVE-2025-68215

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ice: fix PTP cleanup on driver removal in error path<br /> <br /> Improve the cleanup on releasing PTP resources in error path.<br /> The error case might happen either at the driver probe and PTP<br /> feature initialization or on PTP restart (errors in reset handling, NVM<br /> update etc). In both cases, calls to PF PTP cleanup (ice_ptp_cleanup_pf<br /> function) and &amp;#39;ps_lock&amp;#39; mutex deinitialization were missed.<br /> Additionally, ptp clock was not unregistered in the latter case.<br /> <br /> Keep PTP state as &amp;#39;uninitialized&amp;#39; on init to distinguish between error<br /> scenarios and to avoid resource release duplication at driver removal.<br /> <br /> The consequence of missing ice_ptp_cleanup_pf call is the following call<br /> trace dumped when ice_adapter object is freed (port list is not empty,<br /> as it is required at this stage):<br /> <br /> [ T93022] ------------[ cut here ]------------<br /> [ T93022] WARNING: CPU: 10 PID: 93022 at<br /> ice/ice_adapter.c:67 ice_adapter_put+0xef/0x100 [ice]<br /> ...<br /> [ T93022] RIP: 0010:ice_adapter_put+0xef/0x100 [ice]<br /> ...<br /> [ T93022] Call Trace:<br /> [ T93022] <br /> [ T93022] ? ice_adapter_put+0xef/0x100 [ice<br /> 33d2647ad4f6d866d41eefff1806df37c68aef0c]<br /> [ T93022] ? __warn.cold+0xb0/0x10e<br /> [ T93022] ? ice_adapter_put+0xef/0x100 [ice<br /> 33d2647ad4f6d866d41eefff1806df37c68aef0c]<br /> [ T93022] ? report_bug+0xd8/0x150<br /> [ T93022] ? handle_bug+0xe9/0x110<br /> [ T93022] ? exc_invalid_op+0x17/0x70<br /> [ T93022] ? asm_exc_invalid_op+0x1a/0x20<br /> [ T93022] ? ice_adapter_put+0xef/0x100 [ice<br /> 33d2647ad4f6d866d41eefff1806df37c68aef0c]<br /> [ T93022] pci_device_remove+0x42/0xb0<br /> [ T93022] device_release_driver_internal+0x19f/0x200<br /> [ T93022] driver_detach+0x48/0x90<br /> [ T93022] bus_remove_driver+0x70/0xf0<br /> [ T93022] pci_unregister_driver+0x42/0xb0<br /> [ T93022] ice_module_exit+0x10/0xdb0 [ice<br /> 33d2647ad4f6d866d41eefff1806df37c68aef0c]<br /> ...<br /> [ T93022] ---[ end trace 0000000000000000 ]---<br /> [ T93022] ice: module unloaded
