Null Pointer Dereference Vulnerability in Linux Kernel Affecting Trace Events
CVE-2023-53005
5.5MEDIUM
What is CVE-2023-53005?
A vulnerability in the Linux kernel's handling of trace events may lead to null pointer dereference. This occurs when the 'create_hist_field' function is called recursively, potentially returning a NULL value without proper checks. To mitigate this risk, it is crucial to check the return value of 'create_hist_field' to ensure system stability and security. This issue emphasizes the importance of thorough validation in kernel development to prevent crashes and maintain system integrity.
