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 iouring/waitid operation not clearing the waitid information before copying it to the user...

CVE-2026-46315

In the Linux kernel, the following vulnerability has been resolved: iouring/waitid: clear waitid info before copying it to userspace IORINGOPWAITID stores its result fields in struct iowaitid::info and later copies them to userspace siginfo. The prep path initializes the request arguments, but it...

kernel: io_uring/rsrc: reject zero-length fixed buffer import

A flaw was found in the Linux kernel's iouring subsystem. A local attacker can exploit a vulnerability in the ioimportfixed function by importing a zero-length fixed buffer. This can lead to an out-of-bounds read from slab memory, potentially resulting in information disclosure or a denial of...

Linux Distros Unpatched Vulnerability : CVE-2026-45975

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: ublk: use READONCE to read struct ublksrvctrlcmd struct ublksrvctrlcmd is part of the...

CVE-2026-45962

A flaw was found in the Linux kernel's userspace block ublk driver. This vulnerability allows a local attacker to cause an out-of-boundary memory access by providing a specially crafted command that bypasses the IOURINGFSQE128 flag check. This could lead to a system crash, resulting in a denial o...

CVE-2026-45995

A flaw was found in the Linux kernel's iouring/zcrx subsystem. This use-after-free UAF vulnerability occurs because the iofreerbufring function uses a struct userstruct that is prematurely freed by iozcrxifqfree before the ring is destroyed. A local attacker could potentially exploit this flaw to...

CVE-2026-45995

A CVE-2026-45995 has been resolved in the Linux kernel for a local, low-privilege UAF issue in io_uring zcrx handling (io_free_rbuf_ring with a user_struct, freed by io_zcrx_ifq_free before ring destruction). The advisory for openSUSE Tumbleweed indicates the fix is delivered via kernel-devel-7.0...

CVE-2026-45975

CVE-2026-45975 is a Linux kernel vulnerability in the ublk subsystem where a race condition can occur reading struct ublksrv_ctrl_cmd from userspace-mapped memory in the io_uring_sqe. The fix uses READ_ONCE() to copy ublksrv_ctrl_cmd from the io_uring_sqe to a local stack copy and then operates o...
