Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to a memory leak in the Linux kernel when closing a socket. Specifically, the vsock/virtio component fails to free queued packets, leading to a memory leak. This w...

The vulnerability in the socket implementation with address mapping AF_VSOCK in Linux kernel allows attackers to escalate their privileges.

The vulnerability in the socket implementation with AFVSOCK addressing net/vmwvsock/afvsock.c in the Linux kernel is related to synchronization errors when using shared resources. Exploiting this vulnerability can allow an attacker to gain increased privileges...

A local privilege escalation was discovered in the Linux kernel before 5.10.13. Multiple race conditions in the AF_VSOCK implementation are caused by wrong locking in net/vmw_vsock/af_vsock.c. The race conditions were implicitly introduced in the commits that added VSOCK multi-transport support.
