UBUNTU-CVE-2023-52927

In the Linux kernel, the following vulnerability has been resolved: netfilter: allow exp not to be removed in nfctfindexpectation Currently nfconntrackin calling nfctfindexpectation will remove the exp from the hash table. However, in some scenario, we expect the exp not to be removed when the...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the nfctfindexpectation function not removing exp, which could result in ct's being created that are not...

DEBIAN-CVE-2022-49561

In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: re-fetch conntrack after insertion In case the conntrack is clashing, insertion can free skb-nfct and set skb-nfct to the already-confirmed entry. This wasn't found before because the conntrack entry and the...
