CVE-2026-53270

In the Linux kernel, the following vulnerability has been resolved: ipvs: clear the svc scheduler ptr early on edit ipvseditservice while unbinding the old scheduler clears the svc-scheduler ptr after the scheduler module initiates RCU callbacks. This can cause packets to use the old scheduler at...

CVE-2026-53270

The CVE-2026-53270 issue affects the Linux kernel IP Virtual Server (IPVS). During ip_vs_edit_service(), unbinding the old scheduler did not clear the svc->scheduler pointer early enough, so packets could reference freed sched_data after the RCU grace period. The documented fix clears the poin...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ipvs: fixed the NULL pointer dereference in the route error path of ipv4 null-ptr-deref. The IPv4 code path in ipvsgetoutrt calls dstlinkfailure, without ensuring that skb-dev is set. This leads to a NULL pointer dereference in...

SUSE CVE-2026-45850

In the Linux kernel, the following vulnerability has been resolved: ipvs: skip ipv6 extension headers for csum checks Protocol checksum validation fails for IPv6 if there are extension headers before the protocol header. iph-len already contains its offset, so use it to fix the problem...

CVE-2026-45917

In the Linux kernel, the following vulnerability has been resolved: ipvs: do not keep destdst if dev is going down There is race between the netdev notifier ipvsdstevent and the code that caches dst with dev that is going down. As the FIB can be notified for the closed device after our handler...

CVE-2026-45917

The CVE-2026-45917 issue affects the Linux kernel IP Virtual Server (IPVS) component, where a race between the netdev notifier and the destination cache for a closing device could leak a device reference until the destination is removed. Root cause: the code caches dest_dst with a device that is ...

CVE-2026-45850

CVE-2026-45850 pertains to the Linux kernel vulnerability where protocol checksum validation for IPv6 could fail if there are extension headers before the IPv6 header. The confirmed fix uses iph->len as the offset to skip extension headers when performing checksum validation. Technical details...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the ipvs module failing to skip the extended header when calculating the IPv6 checksum. This coul...
