"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ni2c: dev: prevent integer overflow in I2C_TIMEOUT ioctl\n\nWhile fuzzing with Syzkaller, a persistent `schedule_timeout: wrong\ntimeout value` warning was observed, accompanied by SMBus controller\nstate machine corruption.\n\nThe I2C_TIMEOUT ioctl accepts a user-provided timeout in multiples of\n10 ms. The user argument is checked against INT_MAX, but it is\nsubsequently multiplied by 10 before being passed to msecs_to_jiffies().\n\nA malicious user can pass a large value (e.g., 429496729) that passes\nthe `arg > INT_MAX` check but overflows when multiplied by 10. This\nresults in a truncated 32-bit unsigned value that bypasses the\ninternal `(int)m < 0` check in `msecs_to_jiffies()`.\n\nThe truncated value is then assigned to `client->adapter->timeout`\n(a signed 32-bit int), which is reinterpreted as a negative number.\nWhen passed to wait_for_completion_timeout(), this negative value\nundergoes sign extension to a 64-bit unsigned long, triggering the\n`schedule_timeout` warning and causing premature returns. This leaves\nthe SMBus state machine in an unrecoverable state, constituting a\nlocal Denial of Service (DoS).\n\nFix this by bounding the user argument to `INT_MAX / 10`.\n\n[wsa: move the comment as well]"
