CVE-2025-21333-POC 利用 vkrnlintvsp.sys 中的 CVE-2025-21333 的概念验证（不太可靠，请参阅“要求与限制”部分）。参考章节中提供了一些非常有用的资源，适合想要研究该漏洞的人。 漏洞及利用的详细分析可见此处。 该漏洞已被检测到被威胁行为者积极利用。 已在 Windows 11 23h2 上测试。 也可能在 Windows 11 24h2 上工作，但我没有测试。 以下是用于测试 POC 的 ntoskrnl.exe 和 vkrnlintvsp.sys 的哈希值。 PS C:\Windows\System32\drivers get-fileha...

CVE-2026-97953

A flaw was found in the Linux kernel's stmmac network driver. An attacker can cause a Denial of Service DoS by transmitting highly fragmented network packets that use TCP Segmentation Offload TSO. Due to an improper calculation of required transmit descriptors, the driver writes past available...

SUSE CVE-2026-97617

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Check resizedisabled before publishing the new subbuf order ringbuffersubbuforderset stores the new order and only then walks the CPUs, returning -EBUSY if any of them has resizing disabled. A user mapped buffer has...

CVE-2026-97617

A flaw was found in the Linux kernel's ring buffer subsystem. A race condition occurs when updating the buffer configuration concurrently with memory mapping operations. Because the kernel applies the new buffer order before verifying that resizing is permitted across all processors, the system c...

CVE-2026-97573

A flaw was found in the Linux kernel's Broadcom NetXtreme-E bnxten network driver. The driver fails to verify memory allocation success during receive ring buffer resets, ignoring failure responses when memory is low. A local user or network event that triggers a reset under memory exhaustion can...

CVE-2026-97572

A flaw was found in the Linux kernel's Broadcom NetXtreme bnxten network driver. This flaw can result in a Denial of Service DoS or memory corruption when the device is initialized or reset under low-memory conditions. The driver ignores memory allocation errors during receive ring buffer setup a...

CVE-2026-98057

A flaw was found in the Linux kernel's tracing ring buffer. The persistent ring buffer validation logic fails to verify that the recorded sub-buffer count matches the expected page count in the metadata. A local attacker capable of manipulating persistent memory metadata could exploit this issue ...

CVE-2026-98057

The Linux kernel contains a vulnerability in the ring-buffer component. The issue arises because the code utilized meta->nr_subbufs without verifying that it correctly matched nr_pages + 1, despite the system assuming these two values were identical. To resolve this, a check was added to the p...
