A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1974)</p> <p>Duoming Zhou discovered that the NFC subsystem in the Linux kernel did not properly prevent context switches from occurring during certain atomic context operations.
