Description
A flaw was found in the Linux kernel's Hisilicon network driver. This use-after-free vulnerability occurs when a socket buffer (skb) is prematurely freed by the napi_gro_receive() function, and then subsequently dereferenced. A local attacker with low privileges could exploit this by triggering specific conditions, leading to a use-after-free error that can result in system instability, denial of service, or potentially arbitrary code execution and privilege escalation.
