Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the use of NULL pointer checks in the archsetshadowstackstatus function within the arm64 GCS...

PT-2026-43743

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the arch set shadow stack status function where error handling is insufficient. The alloc gcs function, which relies on do mmap, returns an error-encoded pointer upon...

PT-2026-43930

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A deadlock can occur during the shadow stack signal frame pop process in the sigreturn operation. The kernel attempts to verify that it is reading actual shadow stack memory by holding t...

PT-2026-43854

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.0.11-1.1 Description In the KVM nSVM component, the nested sync control from vmcb02 function fails to synchronize the int state field, specifically bit 0 SVM INTERRUPT SHADOW MASK, from vmcb02 to the cached...

CVE-2026-45987

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Sync interrupt shadow to cached vmcb12 after VMRUN of L2 After VMRUN in guest mode, nestedsynccontrolfromvmcb02 syncs fields written by the CPU from vmcb02 to the cached vmcb12. This is because the cached vmcb12 is use...

CVE-2026-36538

Netis AC1200 Router NC21 (firmware v4.0.1.4296) is affected by a hard-coded root credential stored in /etc/shadow.sample, with the root password set to root. This enables an attacker with device access to authenticate as root and take full control of the OS. The connected Red Hat/NVD entries corr...

kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A local attacker with privileges on the host system could exploit a vulnerability in how KVM handles shadow page table entries SPTEs during memory-mapped I/O MMIO operations. By manipulating guest page table entrie...

kernel: Read root-owned files as an unprivileged user

A vulnerability was found in the Linux kernel that allows an unprivileged local user to read sensitive files normally restricted to the root user. The flaw occurs during process exit, where a brief window allows an attacker to intercept file access from a privileged process before it fully...
