Description Anten Skrabec 2022-05-12 23:54:00 UTC 
The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag.

I'm keeping this moderate, I see other distros and people doing CVSSv3 scores with C:H I:H A:H , which I don't see how that works...
