kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

CVE-2026-46071

CVE-2026-43133

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Always use vmcb01 in VMLOAD/VMSAVE emulation Commit cc3ed80ae69f "KVM: nSVM: always use vmcb01 to for vmsave/vmload of guest state" made KVM always use vmcb01 for the fields controlled by VMSAVE/VMLOAD, but it missed...

SUSE CVE-2026-43037

In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: clear skb2-cb in ip4ip6err Oskar Kjos reported the following problem. ip4ip6err calls icmpsend on a cloned skb whose cb was written by the IPv6 receive path as struct inet6skbparm. icmpsend passes IPCBskb2 to...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: bcmasp: A memory leak occurs when disabling an interface. When disabling the TX rings, we flush those rings but forget to reclaim the flushed packets. This leads to a memory leak, as we do not free the DMA-mapped buffers. Th...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: The payload size has been sanitized to prevent member overflow. In functions qla27xxcopyfpinpkt and qla27xxcopymultiplepkt, the framesize reported by the firmware is used to calculate the copy length for the...
