UBUNTU-CVE-2021-47558

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: Disable Tx queues when reconfiguring the interface The Tx queues were not disabled in situations where the driver needed to stop the interface to apply a new configuration. This could result in a kernel panic when...

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...

UBUNTU-CVE-2021-47563

In the Linux kernel, the following vulnerability has been resolved: ice: avoid bpfprog refcount underflow Ice driver has the routines for managing XDP resources that are shared between ndobpf op and VSI rebuild flow. The latter takes place for example when user changes queue count on an interface...

CVE-2021-47562 ice: fix vsi->txq_map sizing

In the Linux kernel, the following vulnerability has been resolved: ice: fix vsi-txqmap sizing The approach of having XDP queue per CPU regardless of user's setting exposed a hidden bug that could occur in case when Rx queue count differ from Tx queue count. Currently vsi-txqmap's size is equal t...

CVE-2021-47558

The CVE-2021-47558 issue affects Linux kernel’s net:stmmac driver. The bug occurred because Tx queues were not disabled when stopping an interface to apply new configuration, potentially causing a kernel panic during: (1) reconfiguring queue numbers (ethtool -L), (2) resizing ring buffers (ethtoo...

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-2021-47556 ethtool: ioctl: fix potential NULL deref in ethtool_set_coalesce()

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-2021-47517

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: ethtool: Fix uninitialized number of lanes

In the Linux kernel, the following vulnerability has been resolved: ethtool: Fix uninitialized number of lanes It is not possible to set the number of lanes when setting link modes using the legacy IOCTL ethtool interface. Since 'struct ethtoollinkksettings' is not initialized in this path, drive...

CVE-2021-47438

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix memory leak in mlx5coredestroycq error path Prior to this patch in case mlx5coredestroycq failed it returns without completing all destroy operations and that leads to memory leak. Instead, complete the destroy flo...

CVE-2021-47438

CVE-2021-47438 affects the Linux kernel mlx5 driver; the root cause is a memory leak in net/mlx5e/ mlx5_core_destroy_cq() where on error path the destroy flow may not complete. The patch fixes this by ensuring the full destroy sequence runs before returning an error and by moving mlx5_debug_cq_re...
