kernel: net/sched: act_api: fix possible infinite loop in tcf_idr_check_alloc()

A vulnerability was found in the Linux kernel's networking subsystem in the actapi implementation within the tcfidrcheckalloc function, which lead to a possible infinite loop when multiple actions with the same index are added, causing the second request to block indefinitely while holding the...

CVE-2024-40995

CVE-2024-40995 affects the Linux kernel net/sched: act_api where repeated adds of actions with the same index could hang by causing an infinite loop in tcf_idr_check_alloc. The fix returns -EAGAIN to prevent the loop while preserving documented behavior. Syzbot reported tasks blocked waiting on r...
