Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/cxgb4: Fix potential null-ptr-deref in pass_establish() If get_ep_from_tid() fails to lookup non-NULL value for ep, ep is dereferenced later regardless of whether it is empty. This patch adds a simple sanity check to fix the issue. Found by Linux Verification Center (linuxtesting.org) with SVACE.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a potential null pointer dereference in the Linux kernel's RDMA cxgb4 driver. Specifically, if the function get_ep_from_tid() fails to find a non-NULL endpoint (ep), the code later dereferences ep without checking if it is NULL, which can lead to a crash or undefined behavior. The issue was fixed by adding a sanity check to ensure ep is not NULL before dereferencing.


How can this vulnerability impact me? :

This vulnerability can cause the Linux kernel to crash or behave unpredictably due to a null pointer dereference in the RDMA cxgb4 driver. This could lead to denial of service or system instability on affected systems using this driver.
