USN-5113-1: Linux kernel vulnerabilities
USN-5113-1: Linux kernel vulnerabilities It was discovered that a race condition existed in the Atheros Ath9k WiFi driver in the Linux kernel. An attacker could possibly use this to expose sensitive information (WiFi network traffic). (CVE-2020-3702) Alois Wohlschlager discovered that the overlay file system in the Linux kernel did not restrict private clones in some situations. An attacker could use this to expose sensitive information. (CVE-2021-3732) It was discovered that the btrfs file system in the Linux kernel did not properly handle removing a non-existent device id. An attacker with CAP_SYS_ADMIN could use this to cause a denial of service. (CVE-2021-3739) It was discovered that the Qualcomm IPC Router protocol implementation in the Linux kernel did not properly validate metadata in some situations. A local attacker could use this to cause a denial of service (system crash) or expose sensitive [ more… ]
