CVE-2026-19204

A client may send a WebSocket frame with an unknown opcode and a very large declared payload length, causing Jetty to attempt a large memory allocation and potentially exhaust the JVM heap. This occurs when auto-fragmentation is enabled, as unknown opcodes bypass the normal maximum frame size...

CVE-2026-80793

This Linux kernel vulnerability affects the IPv4 fragmentation path in ip_do_fragment() . When the effective MTU is smaller than the IPv4 header length plus 8, the function passes a zero-length payload to ip_frag_next() , causing the fragmentation state to stall indefinitely. The result is a soft...
