CVE Details

Release Date:2024-07-12

Description


In the Linux kernel, the following vulnerability has been resolved:\nnetpoll: Fix race condition in netpoll_owner_active\nKCSAN detected a race condition in netpoll:\nBUG: KCSAN: data-race in net_rx_action / netpoll_send_skb\nwrite (marked) to 0xffff8881164168b0 of 4 bytes by interrupt on cpu 10:\nnet_rx_action (./include/linux/netpoll.h:90 net/core/dev.c:6712 net/core/dev.c:6822)\n\nread to 0xffff8881164168b0 of 4 bytes by task 1 on cpu 2:\nnetpoll_send_skb (net/core/netpoll.c:319 net/core/netpoll.c:345 net/core/netpoll.c:393)\nnetpoll_send_udp (net/core/netpoll.c:?)\n\nvalue changed: 0x0000000a -> 0xffffffff\nThis happens because netpoll_owner_active() needs to check if the\ncurrent CPU is the owner of the lock, touching napi->poll_owner\nnon atomically. The ->poll_owner field contains the current CPU holding\nthe lock.\nUse an atomic read to check if the poll owner is the current CPU.
