AI-suggested
A fix has been implemented in the Linux kernel to address this issue by changing the way trace event data is handled. Users should update to the fixed kernel versions to remediate this vulnerability.
Description
A vulnerability in the Linux kernel's ice network driver was resolved to prevent dereferencing invalid pointers in TP_printk() trace events. The issue involved double dereferencing pointers after event recording, which could lead to invalid memory access when printing trace events. This was fixed by copying scalar values into the event instead of dereferencing pointers later.
