kernel: net: bridge: stop fast-leave after deleting a port group

A flaw was found in the Linux kernel's network bridge module. When handling multicast fast-leave, a vulnerability exists where the system may attempt to access a port group after it has been deleted. This can occur if multicast-to-unicast was previously enabled and then disabled, leading to a sta...

kernel: ixgbevf: fix use-after-free in VEPA multicast source pruning

A flaw was found in the Linux kernel's ixgbevf network driver. This vulnerability, a use-after-free, occurs when the driver attempts to process network packets for a specific multicast workaround. An attacker could potentially exploit this by sending specially crafted network traffic, which may...

kernel: ipv6: mcast: Fix use-after-free when processing MLD queries

A flaw was found in the Linux kernel's IPv6 multicast mcast component. When processing Multicast Listener Discovery MLD queries, a pointer to the multicast group address is not correctly reloaded after certain packet manipulations. This can lead to a use-after-free vulnerability, potentially...
