  1. CVE-2026-58302 8.4 Élevée

    LinuxCNC

    rtapi_app in linuxcnc-uspace in LinuxCNC before 2.9.9 allows privilege escalation. It is installed SUID root and loads shared library modules via dlopen() by using a user-supplied module name. Insufficient validation of the module name allows path traversal, enabling an unprivileged local user to load an arbitrary shared library. Because the process retains elevated privileges during module loading, this results in local privilege escalation to root.

  2. CVE-2026-11884 6.5 Moyenne

    Red Hat Directory Server 11 · Red Hat Directory Server 12 · Red Hat Directory Server 13 · Red Hat Enterprise Linux 10

    A heap buffer overflow flaw was found in 389 Directory Server. When serializing objectclass definitions, the oc_superior (SUP) field length is omitted from buffer size calculations in read_schema_dse() and schema_oc_to_string(), but the field is still written via strcat(). An attacker with Directory Manager privileges, or a compromised replication supplier, can trigger a server crash by creating objectclasses with long SUP values. This is an incomplete fix variant of CVE-2025-14905.

  3. CVE-2026-11791 5.0 Moyenne

    Red Hat Directory Server 11 · Red Hat Directory Server 12 · Red Hat Directory Server 13 · Red Hat Enterprise Linux 10

    A flaw was found in 389 Directory Server. During schema reload, the attr_syntax_swap_ht() function unconditionally frees attribute syntax information nodes, bypassing the refcount-based deferred deletion used elsewhere in the attribute syntax subsystem. If an administrator triggers schema reload while concurrent LDAP query traffic is active, worker threads may access freed memory, resulting in use-after-free or double-free and a denial of service (server crash).
