CVE-2026-114651

A memory-handling weakness in the BSON deserialization component of the MongoDB C# Driver allows for potential data leakage. By providing specially crafted serialized input, an unauthenticated party can cause the application to return residual bytes from unrelated data processed earlier on the sa...

CVE-2026-114651 Cross-document data leak via malformed BSON array parsing in reused thread buffer

A memory-handling weakness in the BSON deserialization component of the MongoDB C Driver may cause data left over from previously processed content to be returned when specially crafted serialized input is parsed. An unauthenticated party able to supply serialized data to an application that maps...

SUSE CVE-2026-110354

HAProxy 3 before 3.4.6 allows a remote unauthenticated attacker to cause a denial of service persistent worker-thread CPU exhaustion via an HTTP/1.1 chunked request. Although the H1 multiplexer drains the request before closing the stream, the parser repeatedly re-processes the same bytes without...

CVE-2026-19947 Missing kernel object permission check in devmux syscalls allows unprivileged user threads to retarget a device multiplexer

The device multiplexer pseudo-driver in drivers/misc/devmux/devmux.c exposes two system calls, devmuxselectget and devmuxselectset. When CONFIGUSERSPACE is enabled, their user-mode verifiers zvrfydevmuxselectget and zvrfydevmuxselectset forwarded directly to the kernel implementations without...
