It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. (CVE-2022-2196)

It was discovered that a use-after-free vulnerability existed in the SGI GRU driver in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3424)

Ziming Zhang discovered that the VMware Virtual GPU DRM driver 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). (CVE-2022-36280)

Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel did not properly perform reference counting in some situations, 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-2022-41218)

Gerald Lee discovered that the USB Gadget file system implementation in the Linux kernel contained a race condition, leading to a use-after-free vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-4382)

It was discovered that the NTFS file system implementation in the Linux kernel did not properly validate attributes in certain situations, leading to an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-48423)

It was discovered that the NTFS file system implementation in the Linux kernel did not properly validate attributes in certain situations, leading to an out-of-bounds read vulnerability. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-48424)

José Oliveira and Rodrigo Branco discovered that the...
