CWE-476

Description

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 ->recv_mutex is held. So it is important to hold that mutex. Otherwise a sysfs read can trigger an oops. Commit 17f09d3f619a ("SUNRPC: Check if the xprt is connected before handling sysfs reads") appears to attempt to fix this problem, but it only narrows the race window.

Affected configurations

• linux linux kernel (>= 5.10.67 < 5.11) • linux linux kernel (>= 5.13.19 < 5.16.10) • linux linux kernel 5.17
