In the Linux kernel, the following vulnerability has been resolved: ceph: Do not leak snaprwsem when handlecapgrant is called on an IMPORT operation. When handlecapgrant is called on an IMPORT operation, the snaprwsem resource is held, and the function is expected to release it before returning...

Astra Linux – Vulnerability in Ceph

A key length flaw was discovered in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed during the encryption algorithm process, resulting in the creation of a non-random key. Such a key is weaker and can be exploited to compromise the confidentiality...
