CVE-2023-53335
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.
Does this matter?
Lower severity and a low EPSS score (0.48%). Track it; it rarely justifies an emergency change on its own.
