SUSE CVE-2021-47224

In the Linux kernel, the following vulnerability has been resolved: net: lltemac: Make sure to free skb when it is completely used With the skb pointer piggy-backed on the TX BD, we have a simple and efficient way to free the skb buffer when the frame has been transmitted. But in order to avoid...

kernel: Linux kernel (soundwire): Memory corruption due to incorrect device enumeration completion

A flaw was found in the Linux kernel's soundwire subsystem. The code responsible for managing device enumeration completion, which allows drivers to synchronize with soundwire devices, contains a defect. This issue can lead to memory corruption if drivers are still waiting for completion, as the...

kernel: RDMA/efa: Fix wrong resources deallocation order

In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fix wrong resources deallocation order When trying to destroy QP or CQ, we first decrease the refcount and potentially free memory regions allocated for the object and then request the device to destroy the object. If t...
