General Protection Fault in Linux Kernel's IVPU Component

CVE-2024-54455

Summary

A vulnerability in the Linux kernel's IVPU component has been identified that could potentially lead to a general protection fault. This issue arises when the system attempts to access the fields of a context (ctx) that has not been verified as non-NULL. To mitigate this flaw, the kernel now includes a validation check, ensuring that the ctx is properly initialized before any attempts to access its fields. This fix is crucial for maintaining the stability and security of the system, preventing unexpected crashes and potential exploit scenarios.
