USN-4526-1: Linux kernel vulnerabilities It was discovered that the AMD Cryptographic Coprocessor device driver in the Linux kernel did not properly deallocate memory in some situations. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-18808) It was discovered that the Conexant 23885 TV card device driver for the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19054) It was discovered that the ADIS16400 IIO IMU Driver for the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19061) It was discovered that the AMD Audio Coprocessor driver for the Linux kernel did not properly deallocate memory in certain error conditions. A [ more… ]

USN-4527-1: Linux kernel vulnerabilities It was discovered that the Conexant 23885 TV card device driver for the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19054) It was discovered that the Atheros HTC based wireless driver in the Linux kernel did not properly deallocate in certain error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19073, CVE-2019-19074) Yue Haibing discovered that the Linux kernel did not properly handle reference counting in sysfs for network devices in some situations. A local attacker could possibly use this to cause a denial of service. (CVE-2019-20811) It was discovered that the F2FS file system in the Linux kernel did not properly perform bounds checking in some situations, leading to an [ more… ]

USN-4525-1: Linux kernel vulnerabilities It was discovered that the AMD Cryptographic Coprocessor device driver in the Linux kernel did not properly deallocate memory in some situations. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-18808) It was discovered that the Conexant 23885 TV card device driver for the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19054) It was discovered that the VFIO PCI driver in the Linux kernel did not properly handle attempts to access disabled memory spaces. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-12888) It was discovered that the state of network RNG in the Linux kernel was potentially observable. A remote attacker could use this to [ more… ]

USN-4524-1: TNEF vulnerabilities Paul Dreik discovered that TNEF incorrectly handled filenames. If a user were tricked into opening a specially crafted email attachment, an attacker could possibly use this issue to write arbitrary files to the filesystem or cause TNEF crash, resulting in a denial of service.
