kernel: pppoe: reload header pointer after dev_hard_header()
A flaw was found in the Linux kernel's PPPoE Point-to-Point Protocol over Ethernet implementation. This vulnerability occurs because a pointer to network packet data is not updated after memory is reallocated, leading to the use of an outdated memory address. An attacker with local access could...
kernel: netfilter: nf_queue: hold bridge skb->dev while queued
A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because a queued bridge packet can retain a freed bridge master in its skb-dev field until it is reinjected. When the packet is later reinjected, the system attempts to use the freed bridge master, leading to a...
kernel: nvme-tcp: reject a read that transferred too few bytes
A flaw was found in the NVMe-TCP implementation of the Linux kernel. This vulnerability occurs when the system completes a data read request even if the connected controller transfers fewer bytes than expected. As a result, the user application receives a mix of legitimate and stale data,...
