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 fact that the spi imx controller is not properly referenced when unbinding, potentially leadi...

Linux Distros Unpatched Vulnerability : CVE-2026-45996

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - spi: imx: fix use-after-free on unbind The SPI subsystem frees the controller and any subsystem allocated driver data as part of deregistration unless the...

PT-2026-54812

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A NULL pointer dereference occurs during the probe process in the pinctrl mcp23s08 driver. This happens because regmap initialization triggers the regcache maple populate function, which...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: PCI/pwrctrl: Cancel outstanding rescan work when unregistering. It is possible to trigger a use-after-free situation here by: a forcing rescanworkfunc to take a long time, and b using a pwrctrl driver that may be unloaded for som...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: spi: Fixed a use-after-free of the addlock mutex Commit 6098475d4cb4 “spi: Fixed a deadlock when adding SPI controllers on SPI buses” introduced a per-controller mutex. However, the mutexunlock call for that lock occurs after the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: arm64: dts: qcom: sc7280: Mark PCIe controller as cache coherent. If the controller is not marked as cache coherent, then the kernel will try to ensure coherence during DMA operations, which may lead to data corruption. Therefore...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: spi: microchip-core: Ensure that the TX and RX FIFOs are empty at the start of a transfer. When transmitting with rxlen == 0, the RX FIFO will not be emptied in the interrupt handler. As a result, the next transfer might read dat...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: perf/x86/intel/uncore: Fixed the issue where dieid was initialized and bugs were looked up. In snbeppci2phymapinit, in the case where nrnodeids 8, uncoredevicetodie may return -1 when all CPUs associated with the UBOX device a...

EUVD-2025-209863

Improper input validation in the AMD Secure Processor ASP PCI driver could allow a local attacker to trigger a Use-After-Free UAF condition, potentially resulting in a loss of platform integrity or crash...

PT-2026-41227

Improper Input validation in the AMD Secure Processor ASP PCI driver may allow a local attacker to create a buffer overflow condition, potentially resulting in a crash or denial of service...

SUSE CVE-2026-43319

In the Linux kernel, the following vulnerability has been resolved: spi: spidev: fix lock inversion between spilock and buflock The spidev driver previously used two mutexes, spilock and buflock, but acquired them in different orders depending on the code path: write/read: buflock - spilock ioctl...

EUVD-2026-28754

In the Linux kernel, the following vulnerability has been resolved: nvme-pci: Fix race bug in nvmepollirqdisable In the following scenario, pdev can be disabled between 1 and 3 by 2. This sets pdev-msixenabled = 0. Then, pciirqvector will return MSI-X IRQ15 for 1 whereas return INTx IRQcqvector...

CVE-2026-43460

In the Linux kernel, the following vulnerability has been resolved: spi: rockchip-sfc: Fix double-free in remove callback The driver uses devmspiregistercontroller for registration, which automatically unregisters the controller via devm cleanup when the device is removed. The manual call to...

CVE-2026-43313

In the Linux kernel, the following vulnerability has been resolved: ACPI: processor: Fix NULL-pointer dereference in acpiprocessorerratapiix4 In acpiprocessorerratapiix4, the pointer dev is first assigned an IDE device and then reassigned an ISA device: dev = pcigetsubsys...,...

SUSE CVE-2026-43213

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: pci: validate sequence number of TX release report Hardware rarely reports abnormal sequence number in TX release report, which will access out-of-bounds of wdring-pages array, causing NULL pointer dereference. BUG:...

A UEFI System with SPDM to Protect against Unauthorized Device Connections

Attackers willing to compromise computing systems can use malicious peripherals as an attack vector, threatening users that cannot verify the hardware's authenticity. To address this problem, our work uses the Security Protocol and Data Model to propose a UEFI system capable of authenticating PCI...

CVE-2026-43211

A flaw was found in the Linux kernel. An error in the PCI Peripheral Component Interconnect subsystem's lock management, specifically within the pcislottrylock function, can lead to system instability. This occurs when a lock is incorrectly released, potentially causing warnings or interfering wi...

CVE-2026-43147

A flaw was found in the Linux kernel. A local user can cause a system deadlock by performing specific operations related to SR-IOV Single Root I/O Virtualization device removal.
