CVE-2021-47517

In the Linux kernel, the following vulnerability has been resolved: ethtool: do not perform operations on net devices being unregistered There is a short period between a net device starts to be unregistered and when it is actually gone. In that time frame ethtool operations could still be...

CVE-2021-47517

CVE-2021-47517 affects the Linux kernel’s ethtool handling: during net-device unregistration a reference to the device can be used, enabling operations after unregister begins. The fix moves the operation into an rtnl-locked path on the netlink side so the net device won’t be found post-unregiste...

kernel: ipv4: denial of service when destroying a network interface

A security flaw was found in the Linux kernel's networking subsystem that destroying the network interface with huge number of ipv4 addresses assigned keeps "rtnllock" spinlock for a very long time up to hour. This blocks many network-related operations, including creation of new incoming ssh...
