Overview

AI description

Automated description summarized from trusted sources.

CVE-2024-50264 is a vulnerability in the Linux kernel, specifically within the vsock/virtio subsystem. It arises from a dangling pointer issue during loopback communication. A dangling pointer can be created in `vsk->trans`, potentially leading to a Use-After-Free condition. The vulnerability occurs because the `vsk->trans` pointer is not properly initialized. The fix involves initializing `vsk->trans` to NULL, which prevents the use of the dangling pointer and resolves the Use-After-Free condition.

Description: In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans During loopback communication, a dangling pointer can be created in vsk->trans, potentially leading to a Use-After-Free condition. This issue is resolved by initializing vsk->trans to NULL.
