  3. CVE-2022-48754
In the Linux kernel, the following vulnerability has been resolved: phylib: fix potential use-after-free Commit bafbdd527d56 ("phylib: Add device reset GPIO support") added call to phy_device_reset(phydev) after the put_device() call in phy_detach(). The comment before the put_device() call says that the phydev might go away with put_device(). Fix potential use-after-free by calling phy_device_reset() before put_device().

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: phylib: corrige el posible use-after-free. Commit bafbdd527d56 ("phylib: agregue soporte GPIO para restablecer el dispositivo") se agregó una llamada a phy_device_reset(phydev) después de la llamada put_device() en phy_detach( ). El comentario antes de la llamada put_device() dice que phydev podría desaparecer con put_device(). Solucione el posible use-after-free llamando a phy_device_reset() antes de put_device().
