Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the macb driver not properly logging off the fixed-rate clock, resulting in a resource leak...

PT-2026-36431

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A resource leak occurs in the net: macb component. Resources allocated using the clk register fixed rate function are not properly released because the clk unregister fixed rate function...

SUSE CVE-2026-31574

In the Linux kernel, the following vulnerability has been resolved: clockevents: Add missing resets of the nexteventforced flag The prevention mechanism against timer interrupt starvation missed to reset the nexteventforced flag in a couple of places: - When the clock event state changes. That ca...

CVE-2026-31655

A flaw was found in the Linux kernel. This vulnerability occurs because the NOCHDCP clock, which is part of the pmdomain: imx8mp-blk-ctrl module, is not consistently enabled. This can disrupt the NoC ADB400 port power down handshake, potentially leading to a system hang. The primary impact is a...

CVE-2026-31574

A flaw was found in the Linux kernel's clock event handling. Missing resets of a critical flag can lead to timer interrupt starvation and system stalls. This vulnerability could allow an attacker to cause a denial of service DoS by making the system unresponsive. Mitigation Mitigation for this...

CVE-2026-31655

CVE-2026-31655 affects the Linux kernel’s pmdomain: imx8mp-blk-ctrl module, where the NOC_HDCP clock must be kept enabled. The underlying issue is an inconsistent clock state that can disrupt the NoC ADB400 port power‑down handshake, potentially causing a system hang. Reported impact is a DoS-lik...

That ca...

CVE-2026-31574

CVE-2026-31574 concerns the Linux kernel clockevents subsystem. The issue arises from missing resets of the next_event_forced flag in several code paths, including during clock event state changes, when arming a non-forced event, and in the suspend wakeup handler. This can leave the flag stale ac...

PT-2026-34926

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw in the clockevents prevention mechanism against timer interrupt starvation occurs because the next event forced flag is not reset in certain scenarios. This failure happens when t...

PT-2026-35007

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the pmdomain: imx8mp-blk-ctrl component where the NOC HDCP clock may be disabled, potentially causing a system hang due to the NoC ADB400 port power down handshake...
