Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mm, swap: fixed a potential UAF issue related to VMA readahead. Since commit 78524b05f1a3 “mm, swap: avoiding redundant swap device pinning”, the common helper function for allocating and preparing a swap entry in the swap cache...

CVE-2026-43434

A flaw was found in the rustbinder component of the Linux kernel. When installing or zapping pages, rustbinder may incorrectly look up and use a Virtual Memory Area VMA if it has been closed and replaced at the same address. This can allow a local attacker to write to normally read-only binder...

EUVD-2026-28740

In the Linux kernel, the following vulnerability has been resolved: rustbinder: check ownership before using vma When installing missing pages or zapping them, Rust Binder will look up the vma in the mm by address, and then call vminsertpage or zappagerangesingle. However, if the vma is closed an...

UBUNTU-CVE-2026-43433

In the Linux kernel, the following vulnerability has been resolved: rustbinder: avoid reading the written value in offsets array When sending a transaction, its offsets array is first copied into the target proc's vma, and then the values are read back from there. This is normally fine because th...

CVE-2026-43434

CVE-2026-43434 (Linux kernel, rust_binder) : A vulnerability in the rust_binder component can occur during page installation or zap_page_range operations. If a VMA at a given address is closed and replaced, rust_binder may look up and use the wrong VMA, potentially allowing writes to normally rea...

CVE-2026-43433 rust_binder: avoid reading the written value in offsets array

In the Linux kernel, the following vulnerability has been resolved: rustbinder: avoid reading the written value in offsets array When sending a transaction, its offsets array is first copied into the target proc's vma, and then the values are read back from there.

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 lack of checks for vma ownership in rustbinder, allowing pages to be installed into the wrong...

CVE-2026-31787

CVE-2026-31787 affects the Linux kernel, specifically the xen/privcmd mapping flow. The root cause is a double-free in the VMA splitting path when userspace performs partial munmap() on a privcmd mapping. Because privcmd_vm_ops defines .close but not .may_split or .open, the kernel may_split() pe...
