By the Year

: A vulnerability was found in Linux kernel, where a use-after-frees in nouveau’s postclose handler could happen if removing device that is not common to remove video card physically without power-off, but same happens if “unbind” the driver.

This occurs because of an attempt to access the subjective credentials of another task.Our major contribution is the introduction of a classification of methods used to solve vulnerabilities.

  • Use of this information constitutes acceptance for use in an AS IS condition.
  • A vulnerability was found in the Linux kernel in versions prior to v5.
  • Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.
  • Steven J.
  • Pull requests are welcome as well.
