kernel: Linux kernel: Denial of Service in ice driver via ethtool reload

A flaw was found in the Linux kernel's ice driver. A local attacker with low privileges could trigger a null pointer dereference by calling the ethtool utility during a driver reload operation when the Virtual Station Interface VSI is not properly configured. This can lead to a system crash,...

kernel: ice: xsk: prohibit usage of non-balanced queue id

In the Linux kernel, the following vulnerability has been resolved: ice: xsk: prohibit usage of non-balanced queue id Fix the following scenario: 1. ethtool -L $IFACE rx 8 tx 96 2. xdpsock -q 10 -t -z Above refers to a case where user would like to attach XSK socket in txonly mode at a queue id...

kernel: Linux kernel: Denial of Service in ice driver via uninitialized transmit rings

A flaw was found in the Linux kernel's ice network driver. A local user, by changing the number of transmit queues using the ethtool utility, can trigger an issue where newly allocated transmit rings are not properly initialized. This can lead to a null pointer dereference, causing a system crash...
