CVE-2023-28466

A use-after-free flaw was found in the do_tls_getsockopt function in net/tls/tls_main.c in the Transport Layer Security (TLS) in the Network subcompact in the Linux kernel. This flaw allows an attacker to cause a NULL pointer dereference problem due to a race condition.

Mitigation

This flaw can be mitigated by preventing the affected Transport Layer Security (TLS) kernel module from loading during the boot time. Ensure the module is added into the blacklist file.
