Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

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...

In the Linux kernel, the following vulnerability has been resolved: ipvs: Properly dereferencing pe in ipvsaddservice. Use pe directly to resolve the sparse warning: net/netfilter/ipvs/ipvsctl.c:1471:27: Warning: Dereference of the noderef expression...

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

CVE-2026-45917 affects the Linux kernel’s IPVS path. A race between the netdev notifier (ip_vs_dst_event()) and the code that caches a destination with a device that is going down could allow a valid route to be returned and a leaked device reference until dest is removed. The root cause is the p...

CVE-2026-45850

CVE-2026-45850 relates to the Linux kernel’s IPVS handling of IPv6: protocol checksum validation can fail when IPv6 extension headers precede the protocol header. The fix uses iph->len as the offset rather than the previous value, addressing the miscalc that allowed incorrect checksums. Affect...
