In the Linux kernel, the following vulnerability has been resolved: ip6 tunnel: clear skb2-cb in ip6ip6 err ip6ip6 err clones an outer IPv6 ICMP error skb, pulls it to the quoted inner IPv6 packet, and then passes the clone to icmpv6 send. The clone still carries the outer packet's inet6 skb parm...

CVE-2026-74476

A flaw was found in the veth component of the Linux kernel. This vulnerability occurs when a specially crafted network packet, known as a fraglist skb socket buffer, is processed by the veth driver. An attacker could potentially send such a packet, causing the system to misinterpret fragment...

CVE-2026-74263

A flaw was found in the Linux kernel's Wireless Wide Area Network WWAN t7xx driver. The t7xxportctrltx function, which handles control transmissions, fails to validate the return value of skbclone. An attacker with local access could exploit this by triggering a scenario where skbclone returns a...

CVE-2026-72393

A flaw was found in the Linux kernel's fbnic Ethernet driver. When the fbnictxlso function reallocates a socket buffer skb, it fails to update a cached pointer to shared information. This can lead to a use-after-free vulnerability, where the driver attempts to access memory that has already been...
