CVE-2026-15442 Heap use-after-free on read during bidirectional (D)TLS shutdown

In all builds that make use of DTLS, including default builds, there is a series of conditional states during the TLS shutdown which could lead to a heap-use-after free. If an application ended up getting a partial wolfSSLread which is sometimes caused by a small user buffer passed in, then calle...

PT-2026-97265

Affected versions of connectrpc start a background task to read the request body of every client-streaming and bidirectional-streaming call, before the interceptors or the handler run. A call can finish before it has consumed its request: the handler can return without reading all of its request...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Corrected the migration DMA map direction The SVM DMA device map direction should be set the same as the DMA unmap setting; otherwise, the DMA core will report the following warning. Before finalizing this solution,...

Astra Linux – Vulnerability in RustC

A issue was discovered in the Bidirectional Algorithm in the Unicode Specification through version 14.0. This algorithm allows for the visual reordering of characters through control sequences, which can be used to create source code that implements a logic different from the logical order of...

CVE-2026-68330

CVE-2026-68330 relates to the Linux kernel net/airoha NPU mailbox handling. The issue arises because airoha_npu_send_msg() always maps the mailbox buffer with DMA_TO_DEVICE, while some callers expect the NPU to write the response back into the same buffer. On non‑cache‑coherent architectures (e.g...
