CWE ID 754

Summary

CVE-2024-36481 is a vulnerability affecting the Linux kernel. The issue lies in the tracing/probes subsystem, specifically in the parse_btf_field() function. This function calls btf_find_struct_member() to locate a struct member, but does not adequately handle errors. If btf_find_struct_member() returns an error using the ERR_PTR() macro, parse_btf_field() will only check for a NULL pointer and continue execution. This flaw can lead to unintended behavior or crashes. To mitigate this vulnerability, the error condition must be properly identified using IS_ERR() and propagated up the call stack.
