CVE-2026-53231

In the Linux kernel, the following vulnerability has been resolved: net: phy: don't try to setup PHY-driven SFP cages when using genphy We don't have support for PHY-driver SFP cages with the genphy code. On top of that, it was found by sashiko that running sfpbusaddupstream for genphy deadlocks,...

CVE-2026-53231

CVE-2026-53231 (Linux kernel) : The issue affects the PHY subsystem where PHY-driven SFP cages are not supported with the genphy code. Investigations show that sfp_bus_add_upstream() for genphy can deadlock because PHY probing runs under RTNL for genphy while non-genphy drivers do not. The root c...
