kernel: Linux kernel: Data corruption and system instability due to improper io_uring/net buffer handling

A flaw was found in the Linux kernel's iouring/net component. This vulnerability arises when ring provided buffers are partially committed during network operations, particularly when MSGWAITALL is enabled or with streaming sockets. A local attacker could exploit this by causing multiple socket...

UBUNTU-CVE-2026-23208

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Prevent excessive number of frames In this case, the user constructed the parameters with maxpacksize 40 for rate 22050 / pps 1000, and packsize0 22 packsize1 23. The buffer size for each data URB is maxpacksize...

CVE-2026-23208

CVE-2026-23208 — Linux kernel ALSA USB audio OOB write fix . The issue arose when user-provided ALSA USB audio parameters led to an out-of-bounds write: calculated frames (packsize[0] * packets) exceeded URB buffer, triggering KASAN slab-out-of-bounds in sound/usb/pcm.c. The patch adds a safety c...

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix dmafreecoherent pointer dmaalloccoherent allocates a DMA mapped buffer and stores the addresses in XXXunaligned fields. Those should be reused when freeing the buffer rather than the aligned addresses...

CVE-2026-1837 libjxl: Out-of-bounds write in grayscale color transformation when using LCMS2

A specially-crafted file can cause libjxl's decoder to write pixel data to uninitialized unallocated memory. Soon after that data from another uninitialized unallocated region is copied to pixel data. This can be done by requesting color transformation of grayscale images to another grayscale col...

CVE-2026-2303

The mongo-go-driver repository contains CGo bindings for GSSAPI Kerberos authentication on Linux and macOS. The C wrapper implementation contains a heap out-of-bounds read vulnerability due to incorrect assumptions about string termination in the GSSAPI standard. Since GSSAPI buffers are not...

CVE-2025-61917

n8n is an open source workflow automation platform. From version 1.65.0 to before 1.114.3, the use of Buffer.allocUnsafe and Buffer.allocUnsafeSlow in the task runner allowed untrusted code to allocate uninitialized memory. Such uninitialized buffers could contain residual data from within the sa...

Use of Uninitialized Resource

Overview Affected versions of this package are vulnerable to Use of Uninitialized Resource via the Buffer.allocUnsafe and Buffer.allocUnsafeSlow functions in the task runner process. An attacker can access sensitive in-process memory contents by executing untrusted code that allocates uninitializ...
