Description

A flaw was found in the Linux kernel's mtk_eth_soc driver. This vulnerability occurs when an error in the mtk_open routine within mtk_xdp_setup() leads to an incorrect reset of the eBPF (Extended Berkeley Packet Filter) program pointer without properly decreasing its reference count. This improper resource handling could potentially result in system instability or a denial of service (DoS).

Mitigation

No mitigation is specified in collected source.
