One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.", "published_at": "2019-07-17T13:15:10.687", "modified_at": "2026-06-17T02:16:26.033", "vendor": "Linux", "product": "Linux
