In the Linux kernel, the following vulnerabilities have been resolved: s390/dasd: fixed an issue where error recovery led to data corruption on ESE devices. Extent Space Efficient ESE or thin-provisioned volumes need to be formatted on demand during normal IO processing. The dasdeseneedsformat...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1, and Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: s390/dasd: fixed the issue of double module refcount decrementation. Once the discipline is associated with the device, deleting the device will cause the module’s refcount to be decreased. Performing this operation manually alon...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: s390/dasd: Fixed a potential memory leak in dasdeckdinit. The dasdreservereq resource is allocated before dasdvolinforeq, and it also needs to be freed before the error is returned, just like in the other cases within this...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: s390/dasd: Fixed an Oops in the dasdaliasgetstartdev function due to a missing pavgroup parameter. The Oops occurred because the pavgroup pointer was set to NULL before the function was entered. This allowed a race condition...

Linux Distros Unpatched Vulnerability : CVE-2026-89458

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - s390/dasd: Do not complete a failed ESE read as successful dasdinthandler completes an NRF read of an unallocated ESE track by calling eseread and unconditional...

CVE-2026-89456

A flaw was found in the Linux kernel. Specifically, within the s390/dasd component, an issue exists during error recovery for disk read operations. When a request is partially completed and then recovered, the system fails to correctly propagate the length of the processed data. This can lead to...

CVE-2026-89458

A flaw was found in the Linux kernel's s390/dasd component. The dasdinthandler function incorrectly marks failed Extended Sense Data ESE read operations as successful when processing unallocated ESE tracks. This leads to the block layer receiving stale or uninitialized memory instead of properly...

CVE-2026-89457

A flaw was found in the s390/dasd component of the Linux kernel. An unprivileged local user can trigger a null pointer dereference by reading specific world-readable sysfs attributes while the device is being brought online. This can lead to a kernel panic, resulting in a denial of service...
