USN-5265-1: Linux kernel vulnerabilities
First published: Thu Feb 03 2022(Updated: )
Jeremy Cline discovered a use-after-free in the nouveau graphics driver of the Linux kernel during device removal. A privileged or physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2020-27820) It was discovered that the Bluetooth subsystem 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-2021-3640) Likang Luo discovered that a race condition existed in the Bluetooth subsystem of 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-2021-3752) It was discovered that the SCTP protocol implementation in the Linux kernel did not properly verify VTAGs in some situations. A remote attacker could possibly use this to cause a denial of service (connection disassociation). (CVE-2021-3772) It was discovered that the eBPF implementation in the Linux kernel contained a race condition around read-only maps. A privileged attacker could use this to modify read-only maps. (CVE-2021-4001) It was discovered that the NFS server implementation in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-4090) Felix Wilhelm discovered that the KVM implementation in the Linux kernel did not properly handle exit events from AMD Secure Encrypted Virtualization-Encrypted State (SEV-ES) guest VMs. An attacker in a guest VM could use this to cause a denial of service (host kernel crash) or possibly execute arbitrary code in the host kernel. (CVE-2021-4093) Lin Ma discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel contained a race condition, 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-2021-4202) It was discovered that the AMD Radeon GPU driver in the Linux kernel did not properly validate writes in the debugfs file system. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-42327) 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)
