CVE-2022-48962 is a use-after-free vulnerability in the Linux kernel's Hisilicon Ethernet driver (hisi_femac_rx()). This flaw occurs when a network packet buffer (skb) is freed by napi_gro_receive() but subsequently dereferenced, potentially leading to system instability or arbitrary code execution. With a CVSS score of 7.8 (High), it can be exploited locally with low attack complexity, resulting in high impact to confidentiality, integrity, and availability. Currently, there is no public exploit code available, nor is there evidence of active exploitation or significant community discussion.
