CVE-2025-22101 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: libwx: fix Tx L4 checksum The hardware only supports L4 checksum offload for TCP/UDP/SCTP protocol. There was a bug to set Tx checksum flag for the other protocol that results in Tx ring hang. Fix to compute software checksum for these packets.
A vulnerability in the Linux kernel's networking component, specifically in the libwx library, has been addressed. The issue arose because the hardware only supports Layer 4 (L4) checksum offload for TCP, UDP, and SCTP protocols. A bug caused the transmission (Tx) checksum flag to be incorrectly set for other protocols, leading to a hang in the Tx ring. The vulnerability has been fixed by implementing a software checksum calculation for these affected packets.
