CVE-2026-88265 Crun: crun: /dev/null symlink follow during stdio reopen allows host bind-mount write and chown

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...

CVE-2026-88265

crun (a container runtime) is affected by a flaw where, after pivot_root , reopening /dev/null for stdio can follow a symlink and attach a host file to container stdio, allowing the container to change that file's ownership (chown). This effectively permits a host bind-mount write and chown from ...
