CVE-2026-101303 IPv6 UDP sendto(2) bypasses jail loopback restriction

The IPv6 UDP send path for unconnected sockets did not apply the jail policy of rewriting a loopback destination address to the jail's primary IPv6 address. A process in a classic non-VNET jail can send UDP datagrams to services listening on the host's IPv6 loopback address, bypassing jail networ...

CVE-2026-101303

The FreeBSD kernel contains a vulnerability in the IPv6 UDP send path for unconnected sockets. The system fails to apply the jail policy that rewrites loopback destination addresses to the jail's primary IPv6 address. This allows a process within a classic (non-VNET) jail to send UDP datagrams to...

kernel: netfilter: nfnetlink_queue: do shared-unconfirmed check before segmentation

A flaw was found in the Linux kernel's netfilter nfnetlinkqueue component. This vulnerability occurs when an application does not set the FGSO capability flag and a Generic Segmentation Offload GSO packet with an unconfirmed netfilter connection nfconn entry is received. Due to an incorrect order...

CVE-2026-101303: Incorrectly Specified Destination in a Communication Channel

The IPv6 UDP send path for unconnected sockets did not apply the jail policy of rewriting a loopback destination address to the jail's primary IPv6 address. A process in a classic non-VNET jail can send UDP datagrams to services listening on the host's IPv6 loopback address, bypassing jail networ...

kernel: udp: fix potential use-after-free in tunnel segmentation

A flaw was found in the Linux kernel's UDP User Datagram Protocol tunnel segmentation. This vulnerability arises when the system attempts to process network packets, specifically in the skbudptunnelsegment function. An attacker could potentially exploit a use-after-free condition, where the syste...
