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

FreeBSD FreeBSD Yayım: (24 gün önce)

Açıklama

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 network isolation.

Zayıflık türü (CWE): CWE-941

Veri: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Bilgiler kaynaktaki haliyle, İngilizce yayımlanır.
