CVE-2023-52505

CVE-2023-52505 affects the Linux kernel driver for lynx-28g PHYs. The issue arises when concurrent phy_set_mode_ext() calls target PCC-related protocol-converter registers (PCC8, PCCC, PCCD) across multiple lanes, risking hardware register corruption because lynx_28g_rmw() lacked locking. The fix...
