JSON

A use-after-free vulnerability was found in the Linux kernel’s GPRS Tunneling Protocol ( GTP ) driver, specifically in the gtp_dev_xmit() function. This issue is due to the IPv4 or IPv6 headers not being properly pulled into the skb->head before being accessed. This led to the use of uninitialized values, as reported by Kernel Memory Sanitizer (KMSAN).

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
