A race condition vulnerability in the Linux kernel's proc filesystem was resolved by protecting the ptrace_may_access() function with the exec_update_lock. The issue involved multiple lookups of the task from the pid during ptrace access checks, which could lead to inconsistent or unauthorized access. The fix involves changing the task lookup and locking mechanism to ensure proper synchronization during access checks.
