CVE-2026-45047 bird-lg-go: Fatal Out-of-Memory (OOM) Denial of Service via Unbounded JSON Decoding

bird-lg-go is a BIRD looking glass in Go. Prior to 1.4.5, the apiHandler and similarly webHandlerTelegramBot processes user-provided JSON payloads by directly using json.NewDecoderr.Body.Decode&request without restricting the maximum read size. An unauthenticated remote attacker can stream an...

CVE-2026-45047

The CVE affects the Go project bird-lg-go. Before version 1.4.5, apiHandler (and webHandlerTelegramBot) directly decode user-provided JSON via json.NewDecoder(r.Body).Decode(&request) without a maximum read size, enabling an unauthenticated attacker to stream a very large or endless JSON payload ...

CVE-2026-44988 LibVNCClient Tight Gradient decoding allows malicious server-triggered heap/stack OOB writes

LibVNCClient is a library for easy implementation of a VNC client. In 0.9.15 and earlier, LibVNCClient's Tight encoding decoder uses fixed-size 2048-pixel scratch buffers for the Gradient filter, but it does not reject Tight rectangles whose width is larger than 2048 pixels. A malicious VNC serve...

CVE-2026-45983

In the Linux kernel, the following vulnerability has been resolved: nfsd: never defer requests during idmap lookup During v4 request compound arg decoding, some ops e.g. SETATTR can trigger idmap lookup upcalls. When those upcall responses get delayed beyond the allowed time limit, cachecheck wil...

CVE-2026-45870

CVE-2026-45870 affects the Linux kernel’s SUNRPC auth_gss path. The issue is memory leaks in XDR decoding error paths caused by gssx_dec_ctx(), gssx_dec_status(), and gssx_dec_name() allocating buffers via gssx_dec_buffer()/kmemdup() and returning on error without freeing previously allocated mem...

Refusal Before Decoding: Detecting and Exploiting Refusal Signals in Intermediate LLM Activations

In this paper, we investigate whether refusal behavior can be predicted from LLM intermediate activations before decoding using linear probes trained on residual stream activations at each transformer block. We find that refusal is linearly decodable well before the final layer, indicating that...
