CVE-2026-74379

CVE-2026-74379 affects the Linux kernel dax/kmem driver. The root cause is a partial success in dev_dax_kmem_probe() where at least one resource range is mapped but a subsequent range fails, leading to the range resource being NULL and the probe reporting success. Consequently, dev_dax_kmem_remov...
