In the Linux kernel, the following vulnerability has been resolved:
i40e: fix idx validation in config queues msg
Ensure idx is within range of active/initialized TCs when iterating over
vf->ch[idx] in i40e_vc_config_queues_msg().
A flaw was found in the Linux kernel in the Intel i40e network driver such that in the function i40e_vc_config_queues_msg(), when iterating over vf->ch[idx], the idx value is not properly validated against the range of active/initialized traffic classes (TCs). An attacker with local privileges could supply a malformed value causing an out-of-bounds access, potentially leading to memory corruption, system crash, or possible arbitrary code execution.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
