QEMU: improper IDE controller reset can lead to MBR overwrite
A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead potentially overwriting the VM's boot code. This could be used, for example, by L2 guests with a virtual disk vdiskL2 stored on a virtual disk of an L1 vdiskL1...
CVE-2023-50559
An issue was discovered in XiangShan v2.1, allows local attackers to obtain sensitive information via the L1D cache...
XiangShan Security Breach
XiangShan is an open source high-performance RISC-V processor project open-sourced by XiangShan in China. A security vulnerability exists in XiangShan v2.1, which originated from allowing an attacker to obtain sensitive information through the L1D cache...

SUSE CVE-2014-0145
Multiple buffer overflows in QEMU before 1.7.2 and 2.x before 2.0.0, allow local users to cause a denial of service crash or possibly execute arbitrary code via a large 1 L1 table in the qcow2snapshotloadtmp in the QCOW 2 block driver block/qcow2-snapshot.c or 2 uncompressed chunk, 3 chunk length...
SUSE CVE-2022-3344
A flaw was found in the KVM's AMD nested virtualization SVM. A malicious L1 guest could purposely fail to intercept the shutdown of a cooperative nested guest L2, possibly leading to a page fault and kernel panic in the host L0...
kernel: KVM: x86: Drop WARNs that assert a triple fault never "escapes" from L2
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Drop WARNs that assert a triple fault never "escapes" from L2 Remove WARNs that sanity check that KVM never lets a triple fault for L2 escape and incorrectly end up in L1. In normal operation, the sanity check is...
A flaw was found in the KVM's AMD nested virtualization (SVM). A malicious L1 guest could purposely fail to intercept the shutdown of a cooperative nested guest (L2) possibly leading to a page fault and kernel panic in the host (L0).

kernel: speculation on incompletely validated data on IBM Power9
A flaw was found in the Linux kernel. IBM Power9 processors can speculatively operate on data stored in the L1 cache before it has been completely validated. The attack has limited access to memory and is only able to access memory normally permissible to the execution context. The highest threat...

Multiple Cross Site Scripting XSS vulnerabilities exists in Remote Clinic v2.0 in 1 patients/register-patient.php via the a Contact, b Email, c Weight, d Profession, e refcontact, f address, g gender, h age, and i serial parameters; in 2 patients/edit-patient.php via the a Contact, b Email, c...
kernel: SVM nested virtualization issue in KVM (VMLOAD/VMSAVE)
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2. Due to improper validation of the "virtext" field, this issue could allow a malicious...

KVM 权限许可和访问控制问题漏洞
KVM is a kernel-based virtual machine. A privilege-granting and access-control issue vulnerability exists in KVM's AMD code, which stems from incorrect validation of "intctl" when processing VMCBs Virtual Machine Control Blocks supplied by L1 guests to spawn/process nested guests L2...
hw: L1D Cache Eviction Sampling
A microarchitectural timing flaw was found on some Intel processors. A corner case exists where data in-flight during the eviction process can end up in the “fill buffers” and not properly cleared by the MDS mitigations. The fill buffer contents which were expected to be blank can be inferred usi...
