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 not enabling irq when handling spurious interrupts...

CVE-2024-25744

A flaw was found in the Linux kernel. A VMM can inject external interrupts on any arbitrary vector at any time, which may allow the guest OS to be manipulated from the VMM side. Mitigation This vulnerability can be mitigated by disabling 32-bit emulation by default for TDX and SEV. The user can...

UBUNTU-CVE-2023-46836

The fixes for XSA-422 Branch Type Confusion and XSA-434 Speculative Return Stack Overflow are not IRQ-safe. It was believed that the mitigations always operated in contexts with IRQs disabled. However, the original XSA-254 fix for Meltdown XPTI deliberately left interrupts enabled on two entry...

CVE-2023-46836 x86: BTC/SRSO fixes not fully effective

The fixes for XSA-422 Branch Type Confusion and XSA-434 Speculative Return Stack Overflow are not IRQ-safe. It was believed that the mitigations always operated in contexts with IRQs disabled. However, the original XSA-254 fix for Meltdown XPTI deliberately left interrupts enabled on two entry...

Race Condition

Xen is vulnerable to Race Condition. The vulnerability is caused due to the two mitigations XSA-422 Branch Type Confusion and XSA-434 Speculative Return Stack Overflow not active because it was believed that the mitigations always operated in contexts with IRQs disabled due to original XSA-254 fi...

kernel: x86/i8259: Mark legacy PIC interrupts with IRQ_LEVEL

In the Linux kernel, the following vulnerability has been resolved: x86/i8259: Mark legacy PIC interrupts with IRQLEVEL Baoquan reported that after triggering a crash the subsequent crash-kernel fails to boot about half of the time. It triggers a NULL pointer dereference in the periodic tick code...

PT-2025-54172

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the PCI endpoint test driver where IRQs are freed after the device is removed. This creates a race condition where IRQs could be received with the test device’s memory...

kernel: ASoC: mediatek: mt8173: Enable IRQ when pdata is ready

In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8173: Enable IRQ when pdata is ready If the device does not come straight from reset, we might receive an IRQ before we are ready to handle it. 2.334737 Unable to handle kernel read from unreadable memory at...

SUSE CVE-2007-3720

The process scheduler in the Linux kernel 2.4 performs scheduling based on CPU billing gathered from periodic process sampling ticks, which allows local users to cause a denial of service CPU consumption by performing voluntary nanosecond sleeps that result in the process not being active during ...

SUSE CVE-2011-4915

fs/proc/base.c in the Linux kernel through 3.1 allows local users to obtain sensitive keystroke information via access to /proc/interrupts...

SUSE CVE-2012-2137

Buffer overflow in virt/kvm/irqcomm.c in the KVM subsystem in the Linux kernel before 3.2.24 allows local users to cause a denial of service crash and possibly execute arbitrary code via vectors related to Message Signaled Interrupts MSI, irq routing entries, and an incorrect check by the...

SUSE CVE-2013-1935

A certain Red Hat patch to the KVM subsystem in the kernel package before 2.6.32-358.11.1.el6 on Red Hat Enterprise Linux RHEL 6 does not properly implement the PV EOI feature, which allows guest OS users to cause a denial of service host OS crash by leveraging a time window during which interrup...

SUSE CVE-2013-1952

Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, does not properly check the source when accessing a bridge device's interrupt remapping table entries for MSI interrupts, which allows local guest domains to cause a denial of service interrupt injection via unspecified vector...

SUSE CVE-2015-3291

arch/x86/entry/entry64.S in the Linux kernel before 4.1.6 on the x8664 platform does not properly determine when nested NMI processing is occurring, which allows local users to cause a denial of service skipped NMI by modifying the rsp register, issuing a syscall instruction, and triggering an NM...
