CVE-2026-46113

CVE-2026-46113 (Linux kernel KVM x86 shadow paging use-after-free) is a resolved vulnerability in the KVM shadow paging path. The issue arises when the shadow MMU computes GFNs for direct shadow pages using sp->gfn plus the SPTE index and guest page-table modifications between VM entries can c...

SUSE CVE-2025-71312

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: fix ntfsmountoptions leak in ntfsfillsuper In ntfsfillsuper, the fc-fsprivate pointer is set to NULL without first freeing the memory it points to. This causes the subsequent call to ntfsfsfree to skip freeing the...

SUSE CVE-2026-45958

In the Linux kernel, the following vulnerability has been resolved: drm/exynos: vidi: fix to avoid directly dereferencing user pointer In vidiconnectionioctl, vidi-ediduser pointer is directly dereferenced in the kernel. This allows arbitrary kernel memory access from the user space, so instead o...

SUSE CVE-2026-45971

In the Linux kernel, the following vulnerability has been resolved: bpf: Limit bpf program signature size Practical BPF signatures are significantly smaller than KMALLOCMAXCACHESIZE Allowing larger sizes opens the door for abuse by passing excessive size values and forcing the kernel into expensi...

kernel: mm/page_alloc: clear page->private in free_pages_prepare()

A flaw was found in the Linux kernel's memory management subsystem. When pages are freed, the page-private field is not properly cleared. If these pages are later reallocated as high-order pages and split, the tail pages can retain stale page-private values. This can lead to a use-after-free...

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 direct transmission of rxhashkeylen from RDMA/mana without verification, allowing potential...

CVE-2026-46145: Out-of-bounds Write

In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Validate rxhashkeylen Sashiko points out that rxhashkeylen comes from a uAPI structure and is blindly passed to memcpy, allowing the userspace to trash kernel memory. Bounds check it so the memcpy cannot overflow...

CVE-2026-45958

A flaw was found in the Linux kernel's drm/exynos: vidi driver. A local user could exploit this vulnerability by directly dereferencing a user pointer in the vidiconnectionioctl function. This allows for arbitrary kernel memory access from user space, potentially leading to privilege escalation o...

CVE-2026-46072

A flaw was found in the Linux kernel's ntfs3 module. A local attacker, by mounting a specially crafted NTFS New Technology File System image containing truncated run data, could trigger an out-of-bounds heap read. This vulnerability allows for the disclosure of sensitive information from kernel...
