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...

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...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: rbd: Avoid using memory after it has been freed in dorbdadd, when rbddevcreate fails. If obtaining an ID or setting up a work queue in rbddevcreate fails, a use-after-free occurs on rbddev-rbdclient, rbddev-spec, and rbddev-opts ...

CVE-2026-23047

The CVE-2026-23047 issue affects the Linux kernel’s Ceph client library (libceph). The root cause is that calc_target() clears t->paused when a request should no longer be paused, but never sets it for linger requests; the intended behavior was in __submit_request(), which does not operate on ...
