Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from multiple prepare calls in the q6apm-lpass-dai module, leading to the opening of multiple graphica...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from an error in chip data retrieval in the PowerPC xive architecture. This vulnerability may lead to...

CVE-2026-46042

A flaw was found in the Linux kernel's memory management policy mm/mempolicy component, specifically within the weightedinterleaveautostore function. This vulnerability allows a local user to repeatedly trigger memory leaks by writing specific values. The continuous memory allocation without prop...

CVE-2026-46068

A flaw was found in the Linux kernel's crypto:nx component. This vulnerability involves incorrect memory management during the deallocation of bounce buffers, where an improper function is used. This can lead to memory leaks, which may result in system instability or a Denial of Service DoS...

CVE-2026-46074

A flaw was found in the Linux kernel, specifically within the spi: ch341 driver. This vulnerability occurs during probe failures, leading to memory leaks and use-after-free conditions. These issues can result in system instability or a denial of service, potentially allowing an attacker to impact...

CVE-2026-46093

A flaw was found in the Linux kernel's memory management vmalloc subsystem. The decayvapoolnode function, when invoked concurrently from the shrinker path, lacks proper serialization. This oversight can lead to race conditions, potentially resulting in memory leaks and affecting system stability...

EUVD-2026-32245

In the Linux kernel, the following vulnerability has been resolved: gfs2: fix memory leaks in gfs2fillsuper error path Fix two memory leaks in the gfs2fillsuper error handling path when transitioning a filesystem to read-write mode fails. First leak: kthread objects threadstruct, taskstruct, etc...

CVE-2026-46074

In the Linux kernel, the following vulnerability has been resolved: spi: ch341: fix memory leaks on probe failures Make sure to deregister the controller, disable pins, and kill and free the RX URB on probe failures to mirror disconnect and avoid memory leaks and use-after-free. Also add an...

CVE-2026-46042

In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fix memory leaks in weightedinterleaveautostore weightedinterleaveautostore fetches oldwistate inside the if !input block only. This causes two memory leaks: 1. When a user writes "false" and the current mode is...

CVE-2026-46012

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix memory leaks in rxkadverifyresponse Fix rxkadverifyresponse to free the ticket and the server key under all circumstances by initialising the ticket pointer to NULL and then making all paths through the function after...

First leak: kthread objects threadstruct, taskstruct, etc...

UBUNTU-CVE-2026-46103

In the Linux kernel, the following vulnerability has been resolved: can: ucan: fix devres lifetime USB drivers bind to USB interfaces and any device managed resources should have their lifetime tied to the interface rather than parent USB device. This avoids issues like memory leaks when drivers...
