CVE-2026-18107 Criu: criu: container escape via rseq critical section hijack during checkpoint/restore

A flaw was found in CRIU's handling of restartable sequences rseq during checkpoint/restore. A malicious process inside a container can register an rseq critical section that hijacks CRIU's parasite code injection during checkpoint, allowing it to spoof the process credentials saved in the...

CVE-2026-18107

CRIU vulnerability CVE-2026-18107 involves how CRIU handles restartable sequences (rseq) during checkpoint/restore. A container-embedded process can register an rseq critical section that hijacks CRIU’s parasite code injection, enabling spoofed credentials saved in the checkpoint image. On restor...
