GHSA-5GJJ-XQ44-85R4
Vulnerability from github – Published: 2026-08-05 21:31 – Updated: 2026-08-05 21:31boringproxy through 0.10.0 contains a resource exhaustion vulnerability that allows any authenticated user to permanently exhaust server file descriptors, goroutines, and memory by sending requests to the GET /loading endpoint with attacker-supplied id query parameter values. Because the handler performs no map-lookup validity check and receives on a nil channel that blocks forever, with no timeout, no context cancellation, and no server-side reclamation due to absent HTTP server timeouts, each malicious request permanently holds one goroutine, one file descriptor, and approximately 50 kB of memory until the server's file descriptor limit is reached and listener Accept calls fail, halting all tunnel traffic forwarding for all users.

GHSA-5W2P-JHH5-RPR3
Vulnerability from github – Published: 2024-10-11 18:32 – Updated: 2024-10-11 18:32A Deadlock vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
When a large amount of traffic is processed by ATP Cloud inspection, a deadlock can occur which will result in a PFE crash and restart. Whether the crash occurs, depends on system internal timing that is outside the attackers control.
This issue affects Junos OS on SRX Series:
- All versions before 21.3R3-S1,
- 21.4 versions before 21.4R3,
- 22.1 versions before 22.1R2,
- 22.2 versions before 22.2R1-S2, 22.2R2.

GHSA-9H59-P45G-445H
Vulnerability from github – Published: 2026-03-26 22:13 – Updated: 2026-03-27 21:51Summary
A deadlock in the AMF's SCTP notification handler causes the entire AMF control plane to hang until the process is restarted.
Impact
An attacker with access to the N2 interface can cause Ella Core to hang, resulting in a denial of service for all subscribers.
Fix
Add deferred Radio cleanup in serveConn SCTP server so that every connection exit path removes the radio. Remove the stale-entry scan from SCTP Notification handling.
