CVE-2026-6668 (GCVE-0-2026-6668)

Vulnerability from cvelistv5 – Published: 2026-09-23 16:04 – Updated: 2026-09-23 16:46

Title
Integer overflow causes an infinite loop in packet buffer growth in PgBouncer
Summary
Integer overflow in the packet buffer growth logic in PgBouncer through 1.25.2 allows an unauthenticated remote attacker to cause a denial of service. Sufficiently large input makes the buffer size computation overflow, leaving the growth loop unable to terminate. Because PgBouncer serves all clients from a single process, this saturates a CPU core and stalls every pooled connection until the process is killed. Both unauthenticated and authenticated code paths can reach the overflow.
Severity

Title
infinte loop in libpcap before 1.10.7
Summary
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.
