Rowhammer Attack Against NVIDIA Chips

A new rowhammer attack gives complete control of NVIDIA CPUs. On Thursday, two research teams, working independently of each other, demonstrated attacks against two cards from Nvidia’s Ampere generation that take GPU rowhammering into new--­and potentially much more consequential--­territory: GDD...

CVE-2026-43104

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Fix a memory leak in hang state error path When vc4savehangstate encounters an early return condition, it returns without freeing the previously allocated kernelstate, leaking memory. Add the missing kfree calls by...

CVE-2026-43120 RDMA/irdma: Fix double free related to rereg_user_mr

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix double free related to reregusermr If IBMRREREGTRANS is set during reregusermr, the umem will be released and a new one will be allocated in irdmareregmrtrans. If any step of irdmareregmrtrans fails after the new...

CVE-2026-43104

The CVE-2026-43104 entry concerns the Linux kernel DRM vc4 driver. Root cause: a memory leak in the hang state path where vc4_save_hang_state() could return early without freeing previously allocated kernel_state. Remediation: consolidated early return paths and added missing kfree() calls. Impac...

libpng: libpng: Arbitrary code execution due to use-after-free vulnerability

A flaw was found in libpng, a library used for processing PNG Portable Network Graphics image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can...

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 fact that the iommu vt-d does not check whether PCIe devices are accessible in extended mode,...

PT-2026-37846

A flaw was found in how GLib’s GString manages memory when adding data to strings. If a string is already very large, combining it with more input can cause a hidden overflow in the size calculation. This makes the system think it has enough memory when it doesn’t. As a result, data may be writte...
