kernel: libceph: fix potential use-after-free in have_mon_and_osd_map()

A use-after-free vulnerability was found in the Ceph client session initialization in the Linux kernel. The havemonandosdmap function checks map epochs without holding the appropriate locks, racing with concurrent map updates that free the old map. This can result in dereferencing freed memory...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: rbd: Avoid use-after-free 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. This issue is trigger...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: libceph: The calctarget function should set t-paused, rather than simply clearing it. Currently, calctarget clears t-paused if the request should no longer be paused. However, it never sets t-paused, even though it can determine...

The vulnerability of the do_rbd_add() function in the drivers/block/rbd.c module of the Linux kernel’s block devices driver allows a attacker to cause a service failure.

The vulnerability of the dorbdadd function in the drivers/block/rbd.c module of the Linux kernel’s block devices driver is related to the release of an incorrect pointer. Exploiting this vulnerability could allow an attacker to cause a service failure...

SUSE CVE-2026-68131

In the Linux kernel, the following vulnerability has been resolved: rbd: Reset positive result codes to zero in object map update path In a reply message to an RBD request, a positive result code indicates a data payload, which is not allowed for writes. While rbdosdreqcallback already resets a...

CVE-2026-68131

A flaw was found in the Linux kernel's rbd component. A corrupted reply to an object map update can cause the rbdobjectmapcallback function to process a positive result code, which is not allowed for write operations. This incorrect handling triggers an assertion in rbdobjhandlerequest, leading t...
