Description

A flaw was found in the Linux kernel's BPF (Berkeley Packet Filter) sockmap component when used with kernel TLS (kTLS) receive. A race condition exists where sk_psock_verdict_data_ready() can improperly interact with the kTLS receive process. This can lead to a use-after-free vulnerability, potentially allowing a local attacker to cause a denial of service or achieve arbitrary code execution.
