This check is racy against a concurrent exec() in the target process.  During exec(), a task may transition from a non-privileged binary to a privileged one (e.g., setuid binary) and its credentials/memory mappings may change. If get_robust_list() performs ptrace_may_access() before this transition, it may erroneously allow access to sensitive information after the target becomes privileged.  A racy access allows an attacker to exploit a window during which ptrace_may_access() passes before a target process transitions to a privileged state via exec().  For example, consider a non-privileged task T that is about to execute a setuid-root binary. An attacker task A calls get_robust_list(T) while T is still unprivileged. Since ptrace_may_access() checks permissions based on current credentials, it succeeds. However, if T begins exec immediately afterwards, it becomes privileged and may change its memory mappings. Because get_robust_list() proceeds to access T->robust_list without synchronizing with exec() it may read user-space pointers from a now-privileged process.  This violates the intended post-exec access restrictions and could expose sensitive memory addresses or be used as a primitive in a larger exploit chain. Consequently, the race can lead to unauthorized disclosure of information across privilege boundaries and poses a potential security risk.  Take a read lock on signal->exec_update_lock prior to invoking ptrace_may_access() and accessing the robust_list/compat_robust_list. This ensures that the target task's exec state remains stable during the check, allowing for consistent and synchronized validation of credentials.",null,[],[],[],[14],{"_key":15},"CVE-2025-40341",[],[],[],"2025-12-09T16:17:44.387Z","2026-06-15T19:05:50.991227944Z",{"cisa_kev":22,"cisa_ransomware":22,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[24],{"url":25,"sources":26,"tags":28},"https://security-tracker.debian.org/tracker/CVE-2025-40341",[27],"osv_debian",[29],"Advisory",[],[],[],[34,54],{"ecosystem":35,"name":36,"vendor":37,"product":36,"cpe_part":9,"purl_type":38,"purl_namespace":37,"purl_name":36,"source":9,"versions":39},"Debian","linux","debian","deb",[40,44,48,51],{"version":41,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},"all",true,"ecosystem",{"version":45,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":46,"version_end_type":47,"fixed_in":9},"lt6_1_159_1","6.1.159-1","excluding",{"version":49,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":50,"version_end_type":47,"fixed_in":9},"lt6_12_63_1","6.12.63-1",{"version":52,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":53,"version_end_type":47,"fixed_in":9},"lt6_17_8_1","6.17.8-1",{"ecosystem":35,"name":55,"vendor":37,"product":55,"cpe_part":9,"purl_type":38,"purl_namespace":37,"purl_name":55,"source":9,"versions":56},"linux-6.1",[57],{"version":58,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":59,"version_end_type":47,"fixed_in":9},"lt6_1_159_1~deb11u1","6.1.159-1~deb11u1"]
