CVE-2026-101303

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-2024-26741

CVE-2024-26741 concerns the Linux kernel DCCP/TCP path: when a connect() on an unbound socket occurs, the kernel searches for an ephemeral port, may reuse a bucket in ehash, and marks inet_num. If a concurrent allocation then fails for the corresponding bhash2 bucket, the code must revert by chec...
