phy led triggers

About this tag
The phy led triggers tag on WindowsForum.com covers discussions about Linux kernel PHY LED trigger functionality, including security vulnerabilities and deadlock fixes. A key topic is CVE-2026-23368, an AB-BA deadlock in the networking PHY and LED trigger interaction path that could cause system hangs during device bring-up. The fix involves registering PHY LED triggers during probe instead of phy_attach to resolve unsafe lock ordering between RTNL and triggers_list_lock. While the content is Linux-specific, it may interest Windows users who work with dual-boot systems, virtualization, or embedded environments where Linux networking and LED management are relevant.
