Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: fix potential race condition between napi_init and napi_enable A race condition can happen if netdev is registered, but NAPI isn't initialized yet, and meanwhile user space starts the netdev that will enable NAPI. Then, it hits BUG_ON(): kernel BUG at net/core/dev.c:6423! invalid opcode: 0000 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 417 Comm: iwd Not tainted 6.2.7-slab-dirty #3 eb0f5a8a9d91 Hardware name: LENOVO 21DL/LNVNB161216, BIOS JPCN20WW(V1.06) 09/20/2022 RIP: 0010:napi_enable+0x3f/0x50 Code: 48 89 c2 48 83 e2 f6 f6 81 89 08 00 00 02 74 0d 48 83 ...
