In the Linux kernel, the following vulnerability has been resolved:
net: tls: avoid hanging tasks on the tx_lock
syzbot sent a hung task report and Eric explains that adversarial receiver may keep RWIN at 0 for a long time, so we are not guaranteed to make forward progress. Thread which took txlock and went to sleep may not release txlock for hours. Use interruptible sleep where possible and reschedule the work if it can't take the lock.
Testing: existing selftest passes
