CVE-2026-43060

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftct: drop pending enqueued packets on removal Packets sitting in nfqueue might hold a reference to: - templates that specify the conntrack zone, because a percpu area is used and module removal is possible. - conntra...

CVE-2026-34956

A flaw was found in Open vSwitch. When Open vSwitch is configured with a conntrack flow using FTP helpers over the userspace datapath, a remote attacker can send a specially crafted FTP stream with an EPASV command exceeding 255 characters. This heap access error can lead to a crash, resulting in...

CVE-2026-34956

CVE-2026-34956 affects Open vSwitch: the vulnerability is in the userspace conntrack FTP ALG handler where a crafted FTP payload (EPASV/FTP substrings) can trigger an invalid memory access due to type narrowing when copying FTP substrings. This memory access can crash the process, causing Denial ...

CVE-2026-43027

The CVE-2026-43027 vulnerability in the Linux kernel arises from nf_conntrack_helper_unregister() freeing a helper while expectations still reference it due to NULL data in nf_ct_expect_iterate_destroy(), leading to use-after-free when later access occurs. The fix is to pass the actual helper poi...
