PT-2024-8906

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 5.15.0-rc6+ Description: The issue is related to the ethtool component of the Linux kernel, where there is a short period between a net device starting to be unregistered and when it is actually gone, during whi...

CVE-2021-47517: Use After Free

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-2021-47558: Undefined Security Weakness

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...

CVE-2021-47563: Undefined Security Weakness

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-2021-47241

In the Linux kernel, the following vulnerability has been resolved: ethtool: strset: fix message length calculation Outer nest for ETHTOOLASTRSETSTRINGSETS is not accounted for. This may result in ETHTOOLMSGSTRSETGET producing a warning like: calculated message payload length 684 not sufficient...

SUSE CVE-2021-47241

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...
