Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.50
Description
The vulnerability is related to a use-after-free issue in the
ip6 send skb() function in the Linux kernel's IPv6 implementation. This issue can be exploited to impact the confidentiality, integrity, and availability of protected information. The vulnerability is caused by a slab-use-after-free error in the ip6 send skb() function, which can be triggered by a task attempting to access a freed object. The issue is related to the rawv6 sendmsg() function and the sock sendmsg nosec() function.Recommendations
To resolve this issue, update the Linux kernel to version 6.6.50 or later. As a temporary workaround, consider disabling the
ip6 send skb() function until a patch is available. Restrict access to the vulnerable rawv6 sendmsg() function to minimize the risk of exploitation. Avoid using the sock sendmsg nosec() function in the affected API endpoint until the issue is resolved.Exploit
