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 a problem with dtlaccesslock not being a rwsemaphore in the powerpc/pseries subsystem...
PT-2025-8786
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to the fixed version Description A vulnerability in the Linux kernel has been identified, specifically in the powerpc/pseries/iommu module. The issue arises when the Power Hypervisor allocates an MMIO window that...
The vulnerability of the powerpc/pseries/iommu components in the Linux operating system allows a hacker to cause a service failure.
The vulnerability of the powerpc/pseries/iommu components in the Linux operating system is related to the dereferencing of the NULL pointer. Exploiting this vulnerability can allow an attacker to cause a service failure...
The vulnerability of the Linux operating system’s powerpc/pseries kernel components, which allows a hacker to cause a service failure
The vulnerability of the powerpc/pseries kernel components in the Linux operating system is related to a memory leak. Exploiting this vulnerability can allow an attacker to cause a service failure...
kernel: powerpc: Fix access beyond end of drmem array
A flaw was found in the Linux kernel, specifically affecting the PowerPC architecture's pseries memory hotplug functionality. The issue arises from the dlparmemoryremovebyindex function, which may access memory beyond the bounds of the drmem logical memory block LMB array when it fails to find a...
kernel: powerpc/pseries: Rework lppaca_shared_proc() to avoid DEBUG_PREEMPT
A debug warning issue was found in PowerPC pseries code. When DEBUGPREEMPT is enabled, accessing lppacasharedproc triggers spurious preemption warnings because it uses smpprocessorid in preemptible context...
kernel: powerpc/pseries: Whitelist dtl slub object for copying to userspace
In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: Whitelist dtl slub object for copying to userspace Reading the dispatch trace log from /sys/kernel/debug/powerpc/dtl/cpu- results in a BUG when the config CONFIGHARDENEDUSERCOPY is enabled as shown below. kernel...
kernel: powerpc/pseries/iommu: LPAR panics during boot up with a frozen PE
In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries/iommu: LPAR panics during boot up with a frozen PE At the time of LPAR boot up, partition firmware provides Open Firmware property ibm,dma-window for the PE. This property is provided on the PCI bus the PE is...
kernel: powerpc/pseries: Fix potential memleak in papr_get_attr()
A flaw was found in the Linux kernel. A potential memleak in paprgetattr may lead to compromised availability...
