medium Nessus Plugin ID 232436

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-53215 advisory.

 - In the Linux kernel, the following vulnerability has been resolved: svcrdma: fix miss destroy percpu_counter in svc_rdma_proc_init() There's issue as follows: RPC: Registered rdma transport module.
 RPC: Registered rdma backchannel transport module. RPC: Unregistered rdma transport module. RPC:
 Unregistered rdma backchannel transport module. BUG: unable to handle page fault for address:

If CONFIG_HOTPLUG_CPU is enabled, residual nodes May be in the 'percpu_counters' list. The above issue May occur once the module is removed.
 If the CONFIG_HOTPLUG_CPU configuration is not enabled, memory leakage occurs. To solve above issue just destroy all percpu counters when register_sysctl() return NULL. (CVE-2024-53215)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
