CyberRota Analysis

AI-Generated

The vulnerability affects the Linux kernel's proc filesystem, specifically in the handling of process access controls where the `ptrace_may_access()` function is not adequately protected by the `exec_update_lock`. This oversight could potentially allow unauthorized access to process information, leading to privilege escalation or information disclosure. System administrators and organizations using Linux should prioritize this fix to safeguard against potential exploitation.

Original NVD Description

In the Linux kernel, the following vulnerability has been resolved: proc: protect ptrace_may_access() with exec_update_lock (part 1) Fix the easy cases where procfs currently calls ptrace_may_access() without exec_update_lock protection, where the fix is to simply add the extra lock or use mm_access(): - do_task_stat(): grab exec_update_lock - proc_pid_wchan(): grab exec_update_lock - proc_map_files_lookup(): use mm_access() instead of get_task_mm() - proc_map_files_readdir(): use mm_access() instead of get_task_mm() - proc_ns_get_link(): grab exec_update_lock - proc_ns_readlink(): grab exec_update_lock
