kernel: SUNRPC: lock against ->sock changing during sysfs read

A vulnerability was found in the Linux kernel's SUNRPC component, where a race condition exists during sysfs read operations due to improper handling of the -sock pointer. If the mutex -recvmutex is not held, -sock may change asynchronously, leading to a potential kernel oops. This vulnerability...

SUSE CVE-2022-48816

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: lock against -sock changing during sysfs read -sock can be set to NULL asynchronously unless -recvmutex is held. So it is important to hold that mutex. Otherwise a sysfs read can trigger an oops. Commit 17f09d3f619a...
