UBUNTU-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-2021-47556

In the Linux kernel, the following vulnerability has been resolved: ethtool: ioctl: fix potential NULL deref in ethtoolsetcoalesce ethtoolsetcoalesce now uses both the .getcoalesce and .setcoalesce callbacks. But the check for their availability is buggy, so changing the coalesce settings on a...

CVE-2021-47556

CVE-2021-47556 concerns a NULL-deref in ethtool_set_coalesce() on the legacy ioctl path when a device driver implements only one of get_coalesce() or set_coalesce() and the availability check is buggy. The issue could crash with a NULL pointer when changing coalescing settings if both callbacks a...

CVE-2021-47517 ethtool: do not perform operations on net devices being unregistered

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...
