What to do
AI-suggested
A fix has been implemented in the Linux kernel to disable extts events when PTP is released, preventing the kernel crash and residual event firing. Users should apply the updated kernel version containing this fix once available. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's ice driver related to improper handling of extts events has been fixed. When the driver is removed while the ts2phc application is running, an extts event may remain enabled, potentially causing a kernel crash. Additionally, if the driver is reloaded and the application restarted, residual extts events from a previous run may continue firing, generating unexpected messages. The fix ensures extts events are disabled when the Precision Time Protocol (PTP) is released to prevent these issues.
