Overview

CVE-2024-53210 is a medium-severity vulnerability affecting linux linux_kernel. It was published on December 27, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

s390/iucv: MSG_PEEK causes memory leak in iucv_sock_destruct()

Passing MSG_PEEK flag to skb_recv_datagram() increments skb refcount

(skb->users) and iucv_sock_recvmsg() does not decrement skb refcount

at exit.

This results in skb memory leak in skb_queue_purge() and WARN_ON in

iucv_sock_destruct() during socket close. To fix this decrease

skb refcount by one if MSG_PEEK is set in order to prevent memory

leak and WARN_ON.
