Summary
linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities
Details

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)

Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation did not properly verify certain fragmented frames. A physically proximate attacker could possibly use this issue to inject or decrypt packets. (CVE-2020-26141)

Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation accepted plaintext fragments in certain situations. A physically proximate attacker could use this issue to inject packets. (CVE-2020-26145)

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)

It was discovered a race condition existed in the Unix domain socket implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-0920)

It was discovered that the IPv6 implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-0935)

Zygo Blaxell discovered that the btrfs file system implementation in the Linux kernel contained a race condition during certain cloning operations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2021-28964)

Dan Carpenter discovered that the block device manager (dm) implementation in the Linux kernel contained a buffer overflow in the ioctl for listing devices. A privileged local attacker could use this to cause a denial of service (system crash). (CVE-2021-31916)

It was discovered that the Option USB High Speed Mobile device driver in the Linux kernel did not properly handle error conditions. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-37159)

It was discovered that the network packet filtering implementation in the Linux kernel did not properly initialize information in certain circumstances. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2021-39636)

Jann Horn discovered a race condition in the Unix domain socket implementation in the Linux kernel that could result in a read-after-free. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-4083)

Luo Likang discovered that the FireDTV Firewire driver in the Linux kernel did not properly perform bounds checking in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-42739)

Brendan Dolan-Gavitt discovered that the Marvell WiFi-Ex USB device driver in the Linux kernel did not properly handle some error conditions. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2021-43976)

Amit Klein discovered that the IPv4 implementation in the Linux kernel could disclose internal state in some situations. An attacker could possibly use this to expose sensitive information. (CVE-2021-45486)
