USN-8960-1: Linux kernel (OEM) vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - USB Gadget drivers; - Memory management; - Multiple devices driver; - ARM64 architecture; - EROFS file system; -...

CVE-2026-98821

A flaw was found in the Linux kernel's block layer. A local user could exploit this vulnerability to cause a denial of service DoS by initiating polled direct I/O operations combined with user integrity metadata. Because the kernel improperly attempts to poll integrity metadata as standard block...

CVE-2026-98821

In the Linux kernel, the following vulnerability has been resolved: block: reject polled dio with user integrity metadata IOCBHASMETADATA leaves iocb-private as a uiometa, while iocbbioiopoll expects a bio. Since 2729a60bbfb9, metadata I/O always uses blkdevdirectIO, which never publishes the bio...

CVE-2026-98821

The Linux kernel contains a vulnerability where IOPOLL calls bio_poll() on uio_meta instead of a bio structure when user integrity metadata is present. This occurs because IOCB_HAS_METADATA leaves iocb->private as uio_meta, but iocb_bio_iopoll() expects a bio, and since commit 2729a60bbfb9, me...

CVE-2026-98821: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: block: reject polled dio with user integrity metadata IOCBHASMETADATA leaves iocb-private as a uiometa, while iocbbioiopoll expects a bio. Since 2729a60bbfb9, metadata I/O always uses blkdevdirectIO, which never publishes the bio...

PT-2026-117040

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the block layer where polled direct I/O DIO is not properly handled when combined with user integrity metadata. Specifically, when IOCB HAS METADATA is present,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: In the “block” layer, do not call “rqqosops-donebio” if the bio data structure is not being tracked. The “rqqos” framework is only applied on request-based drivers. Therefore: 1 The “rqqosdonebio” function is not necessary for...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Block layer: Fixed a warning in copyfromiter. Syzkaller reported a warning in copyfromiter because an ioviter was supposedly used in the wrong direction. The reason is that Syzkaller managed to generate a request with a transfer...

Ubuntu 24.04 LTS : Linux kernel (Azure) vulnerabilities (USN-8918-1)

"The remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8918-1 advisory. It was discovered that some AMD processors did not properly perform Reverse Map Table RMP checks when the IOMMU accessed certain host buffers. A local...

SUSE CVE-2026-93257

kernel: block: zero non-PI portion of auto integrity buffer

An information disclosure vulnerability was found in the Linux kernel's block layer integrity handling. When auto-generating integrity buffers for writes with protection information PI enabled, the non-PI portion of the metadata buffer is left uninitialized if the metadata size exceeds the PI tup...
