SUSE CVE-2021-47255

In the Linux kernel, the following vulnerability has been resolved: kvm: LAPIC: Restore guard to prevent illegal APIC register access Per the SDM, "any access that touches bytes 4 through 15 of an APIC register may cause undefined behavior and must not be executed." Worse, such an access in...

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 stack information leak on systems that do not support DMA...

A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information it can be further used to defeat existing kernel protection mechanisms.

SUSE CVE-2010-4525

Linux kernel 2.6.33 and 2.6.34.y does not initialize the kvmvcpuevents-interrupt.pad structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via unspecified vectors...

SUSE CVE-2016-9178

The getuserasmex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not initialize a certain integer variable, which allows local users to obtain sensitive information from kernel stack memory by triggering failure of a getuserex call...

SUSE CVE-2018-17972

An issue was discovered in the procpidstack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents...
