About this tag
Discussions tagged with network availability cover vulnerabilities and bugs that can disrupt network services. Topics include CVE-2023-46752 in FRRouting BGP, which crashes bgpd via malformed MP_REACH_NLRI data; CVE-2025-37945 in Linux PHY/MDIO handling, causing availability issues across suspend/resume cycles; and CVE-2025-40264 in the be2net driver, leading to kernel crashes from a null-pointer dereference. A thread also addresses Remote Desktop connectivity problems on a domain computer, where network availability errors prevent remote access. These posts focus on maintaining reliable network operations through patching, driver updates, and troubleshooting connectivity.
