Summary
Fix CVE(s): CVE-2026-29169
Details
  • SECURITY UPDATE: NULL pointer dereference in mod_dav_lock indirect-lock refresh
    • debian/patches/CVE-2026-29169.patch: replace all six dp-> reads in the indirect-lock branch of dav_generic_refresh_locks() with the resolved dp_scan->... values in modules/dav/lock/locks.c so a crafted WebDAV LOCK refresh against a resource that only inherits an indirect lock from a parent no longer dereferences NULL via dp->locktoken / dp->f.scope / dp->owner. Upstream fix 225dc070adba11040b774cf641e1d8bc79941643 (SVN r1933354).
