UBUNTU-CVE-2021-47562

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...

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...

CVE-2021-47527

Summary: CVE-2021-47527 affects the Linux kernel’s serial core. The root cause was a transmit-buffer not freed on final close after switching to tty_port_close, which could cause the buffer to remain uncleared (stalling ioctl drains) and could leak on driver unbind. The issue has been fixed in th...

kernel: ice: Don't tx before switchdev is fully configured

In the Linux kernel, the following vulnerability has been resolved: ice: Don't tx before switchdev is fully configured There is possibility that iceeswitchportstartxmit might be called while some resources are still not allocated which might cause NULL pointer dereference. Fix this by checking if...

kernel: ixgbe: Fix panic during XDP_TX with > 64 CPUs

A flaw was found in the Linux kernel's ixgbe network driver. On systems with more than 64 CPUs, XDPTX operations can cause a kernel panic due to an array-index-out-of-bounds access. The ixgbexdplockingkey variable can be incorrectly decremented to zero during ring reconfiguration, causing the...

kernel: igc: Fix Kernel Panic during ndo_tx_timeout callback

A race condition was identified in the Intel “igc” network driver in the Linux kernel. Under specific heavy traffic and timing scenarios, such as when the transmit queue times out ndotxtimeout and the adapter reset path is invoked concurrently with device teardown or reinitialization, the driver...
