Description
In the Linux kernel, the following vulnerability has been resolved:
iw_cxgb4: Fix potential NULL dereference in c4iw_fill_res_cm_id_entry()
This condition needs to match the previous "if (epcp->state == LISTEN) {"
exactly to avoid a NULL dereference of either "listen_ep" or "ep". The
problem is that "epcp" has been re-assigned so just testing
"if (epcp->state == LISTEN) {" a second time is not sufficient.
Affected configurations
• linux linux kernel (>= 4.18 < 5.15.99)
• linux linux kernel (>= 5.16 < 6.1.16)
• linux linux kernel (>= 6.2 < 6.2.3)
