CVE-2026-88265: Improper Link Resolution Before File Access

A flaw was found in crun. After pivotroot, reopening /dev/null for stdio can follow a symlink and attach a host file to container stdio, then change that file's ownership. Affected versions are crun 1.29.1 and earlier. Default configurations that mount a fresh /dev are not exposed. No fixed relea...
