In the Linux kernel, the following vulnerability has been resolved: ionic: fix use after netifnapidel When queues are started, netifnapiadd and napienable are called. If there are 4 queues and only 3 queues are used for the current configuration, only 3 queues' napi should be registered and...

SUSE CVE-2024-40937

In the Linux kernel, the following vulnerability has been resolved: gve: Clear napi-skb before devkfreeskbany gverxfreeskb incorrectly leaves napi-skb referencing an skb after it is freed with devkfreeskbany. This can result in a subsequent call to napigetfrags returning a dangling pointer. Fix...
