- Summary
- rxrpc: fix io_thread race in rxrpc_wake_up_io_thread()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
rxrpc: fix iothread race in rxrpcwakeupio_thread()
rxrpcwakeupiothread() checks local->iothread before waking it, but then reloads the pointer for wakeup_process().
local->iothread is cleared with WRITEONCE() when the I/O thread exits, so the second load can see NULL even if the first load did not.
Take a READONCE() snapshot and use it for both the NULL check and the wakeupprocess() call, as rxrpcencap_rcv() already does.
