kernel: netfilter: synproxy: refresh tcphdr after skb_ensure_writable

A flaw was found in the Linux kernel's netfilter synproxy module. When handling TCP timestamp options, a stale pointer can be used after memory reallocation. This can result in memory corruption, where data is written to a freed memory area, or lead to packets being sent with an incorrect checksu...

kernel: udp: fix potential use-after-free in tunnel segmentation

A flaw was found in the Linux kernel's UDP User Datagram Protocol tunnel segmentation. This vulnerability arises when the system attempts to process network packets, specifically in the skbudptunnelsegment function. An attacker could potentially exploit a use-after-free condition, where the syste...

kernel: vhost: reset the vring metadata cache on vring reconfiguration

A flaw was found in the Linux kernel's vhost subsystem. A local attacker could exploit this vulnerability by reconfiguring a virtual ring vring using specific ioctl commands while a device Input/Output Memory Management Unit IOTLB is attached. This improper handling of the vring metadata cache ca...
