Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the OGM aggregation in batman-adv without checking the tail space, potentially leading to skbput overfl...

Linux Distros Unpatched Vulnerability : CVE-2026-31683

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - batman-adv: avoid OGM aggregation when skb tailroom is insufficient When OGM aggregation state is toggled at runtime, an existing forwarded packet may have been...

CVE-2026-31659

A flaw was found in the batman-adv component of the Linux kernel. A remote attacker can exploit this vulnerability by sending a specially crafted oversized global Topology Table TT response. This causes an integer overflow during memory allocation, leading to a heap overflow and memory corruption...

CVE-2026-31657

A flaw was found in the Linux kernel's batman-adv component. The batadvblaaddclaim function can improperly drop a reference to a backbone gateway while other parts of the code, such as the netlink claim dump path, still hold and attempt to use a pointer to the freed memory. This creates a...
