CVE-2024-56701
CVE-2024-56701: Linux kernel powerpc/pseries code fixed a sleeping-lock issue by changing dtl_access_lock to a rw_semaphore because kmalloc() can sleep while held. Root cause: a non-sleeping lock protected code path that sleeps, causing a potential sleep in atomic context. Impact is local (LOCAL)...

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...
