In the Linux kernel, the following vulnerability has been resolved:
watchdog: msc313e: Fix clock leak and spurious timer in settimeout()
msc313e wdt settimeout() unconditionally calls msc313e wdt start() which
introduces two severe bugs:
- If the watchdog is already active, calling start() again will increase the reference count of the clock again. However stop() is only called once, the reference count is unbalance.
- If the watchdog is stopped, calling settimeout() will start the hardware timer accidentally.
Factor out the register-writing logic into a helper function. Only call
it in settimeout() if the watchdog is running. Otherwise, simply update
wdev->timeout. Encontrou algum problema na descrição? Tem algo a acrescentar? Fique à vontade para nos escrever 👾
