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 the rxrpcallocclientcall function acquiring key references without releasing them when the call i...

PT-2026-34917

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A deadlock occurs in the RDMA/irdma component when a netdev reset is executed while RDMA applications are active. The netdev reset leads the ice driver to remove the irdma auxiliary...

CVE-2026-31639: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix key reference count leak from call-key When creating a client call in rxrpcallocclientcall, the code obtains a reference to the key. This is never cleaned up and gets leaked when the call is destroyed. Fix this by...

CVE-2026-31634: Undefined Security Weakness

The vulnerability of the nd_async_device_register() function in the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the ndasyncdeviceregister function in the Linux operating system’s kernel is related to a violation of the count of references to pages displayed in memory. Exploiting this vulnerability can allow an attacker to trigger a service failure...

Oracle Critical Patch Update Advisory - April 2026

A Critical Patch Update is a collection of patches for multiple security vulnerabilities. These patches address vulnerabilities in Oracle code and in third party components included in Oracle products. These patches are usually cumulative, but each advisory describes only the security patches add...

kernel: scsi: target: iscsi: Fix use-after-free in iscsit_dec_session_usage_count()

In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Fix use-after-free in iscsitdecsessionusagecount In iscsitdecsessionusagecount, the function calls complete while holding the sess-sessionusagelock. Similar to the connection usage count logic, the waiter...

CVE-2026-31523

A flaw was found in the Linux kernel's Non-Volatile Memory Express NVMe PCI driver. A local user can trigger a race condition during a system reset by changing the polled queue count. This vulnerability allows a high-priority task to attempt to poll a queue before the system's queue maps are...

April Linux Patch Wednesday

April Linux Patch Wednesday. In April, Linux vendors addressed 1,035 vulnerabilities - nearly twice as many as in March. One might assume that most of these would again be Linux Kernel vulnerabilities, but that's not the case! Linux Kernel vulnerabilities were relatively few - just 209. The...

AZL-83246 CVE-2026-31505 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: iavf: fix out-of-bounds writes in iavfgetethtoolstats iavf incorrectly uses realnumtxqueues for ETHSSSTATS. Since the value could change in runtime, we should use numtxqueues instead. Moreover iavfgetethtoolstats uses...

CVE-2026-31494

In the Linux kernel, the following vulnerability has been resolved: net: macb: use the current queue number for stats There's a potential mismatch between the memory reserved for statistics and the amount of memory written. gemgetssetcount correctly computes the number of stats based on the activ...

AZL-83258 CVE-2026-31489 affecting package kernel for versions less than 6.6.141.1-1

In the Linux kernel, the following vulnerability has been resolved: spi: meson-spicc: Fix double-put in remove path mesonspiccprobe registers the controller with devmspiregistercontroller, so teardown already drops the controller reference via devm cleanup. Calling spicontrollerput again in...

CVE-2026-31523

In the Linux kernel NVMe PCI driver, CVE-2026-31523 is a race condition: a running change to the polled queue count can create a brief window during reset where a hipri task poll occurs before queue maps are updated, risking double completions when the interrupt-driven path takes over. The issue ...
