CVE-2026-6554

A flaw was found in libpcap. The Berkeley Packet Filter BPF interpreter incorrectly handles offsets in 'ja L' instructions, allowing backward jumps without limiting loop iterations. A local attacker could provide a specially crafted filter program, leading to an infinite loop and causing a Denial...

net/http/internal/http2: golang: golang.org/x/net: Go HTTP/2: Denial of Service via malformed SETTINGS_MAX_FRAME_SIZE frame

A flaw was found in the HTTP/2 protocol implementation within the Go standard library golang.org/x/net and net/http/internal/http2. A remote attacker can exploit this vulnerability by sending a specially crafted HTTP/2 SETTINGS frame with the SETTINGSMAXFRAMESIZE parameter set to zero. This...

SUSE CVE-2026-6554

libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to implement looping via backward jumps, but it does not limit the number of loop iterations. In particular uncommon use cases a crafted filter program can cause the interpreter to loop infinitely...
