CVE-2026-46079 rbd: fix null-ptr-deref when device_add_disk() fails

In the Linux kernel, the following vulnerability has been resolved: rbd: fix null-ptr-deref when deviceadddisk fails dorbdadd publishes the device with deviceadd before calling deviceadddisk. If deviceadddisk fails after deviceadd succeeds, the error path calls rbdfreedisk directly and then later...

CVE-2026-46079

CVE-2026-46079 concerns the Linux kernel RBD path. The issue arises when device_add_disk() is followed by a failure in device_add_disk(); the code can call rbd_free_disk() twice and then rbd_dev_device_release(), causing a null-ptr-deref in __blk_mq_free_map_and_rqs() during blk-mq cleanup. The f...
