{"id":"DEBIAN-CVE-2024-56694","details":"In the Linux kernel, the following vulnerability has been resolved:  bpf: fix recursive lock when verdict program return SK_PASS  When the stream_verdict program returns SK_PASS, it places the received skb into its own receive queue, but a recursive lock eventually occurs, leading to an operating system deadlock. This issue has been present since v6.9.
