CVE-ID: CVE-2022-39189
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a guest user to escalate privileges on the system.
The vulnerability exists due to incorrect handling of TLB flush operations in certain KVM_VCPU_PREEMPTED situations in the x86 KVM subsystem in the Linux kernel. An attacker with unprivileged access to the guest OS can escalate privileges on the guest.

CVE-ID: CVE-2022-3061
CWE-ID:
CWE-369 - Divide By Zero
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to missing checks of the "pixclock" value in the Linux kernel i740 driver. A local user can pass arbitrary values to the driver through ioctl() interface, trigger a divide by zero error and perform a denial of service (DoS) attack.

CVE-ID: CVE-2022-2663
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass firewall rules.
