Linux Kernel Vulnerability in QCOM Display Clock Management

CVE-2024-58080

Summary

A vulnerability exists in the Linux kernel's QCOM display clock management where the clk_rcg2 structure lacks a defined parent_map when a parent is assigned. This oversight can result in a NULL pointer dereference during the clk_set_rate function call. To mitigate this issue, the parent_map property must be properly implemented for the clock, alongside un-inline adjustments for parent_data to ensure coherence between matching components.
