CVE-2026-74374

A flaw was found in the Linux kernel's md/raid1 and md/raid10 modules. An issue in detecting the error path when using mdclonedbio can lead to incorrect memory allocation flags. This misallocation can result in a system deadlock under memory pressure, causing a denial of service...

The vulnerability of the drivers/md components of the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the drivers/md components of the Linux operating system’s kernel is related to improper synchronization. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-72437

A flaw was found in the Linux kernel's md/raid1 component. When a read operation is retried with the REQNOWAIT flag set, and the waitreadbarrier function fails, a pre-allocated r1bio structure may not be properly freed. This resource leak can accumulate over time, potentially leading to a denial ...

CVE-2026-74373

A flaw was found in the Linux kernel's md/raid1 and raid10 components. This flaw involves incorrect accounting of block I/O bio operations for split cloned bios. When a failed bio is split and resubmitted, the system may either double count or miss accounting for these bios. This can lead to...

CVE-2026-72440

A flaw was found in the Linux kernel's RAID1 Redundant Array of Independent Disks Level 1 implementation. During write failures, the md/raid1 module may fail to release writespending and barrier references. This oversight can lead to a resource leak, potentially causing system instability or a...

CVE-2026-72439

A flaw was found in the Linux kernel's md/raid10 component. When write requests fail, the raid10writerequest function may not properly release a writespending reference. This resource leak can accumulate over time, potentially leading to a denial of service DoS condition where the system becomes...

CVE-2026-72438

A flaw was found in the Linux kernel's multiple device MD driver, specifically in the RAID10 implementation. This vulnerability occurs due to reference leaks in the writespending and barrier mechanisms during discard failures. An attacker could potentially exploit this by triggering discard...

Linux Distros Unpatched Vulnerability : CVE-2026-74376

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - md/raid10: reset readslot when reusing r10bio for discard putallbios always drops devsi.bio, but it only drops devsi.replbio when r10bio-readslot 0. If discard...

Linux Distros Unpatched Vulnerability : CVE-2026-72437

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - md/raid1: free r1bio when REQNOWAIT is set and read would block on retry When a read is retried, raid1readrequest may be called with a pre-allocated r1bio. If...

The vulnerability in the driver/md/md-bitmap.c component of the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the drivers/md/md-bitmap.c component in the Linux operating system is related to the simultaneous execution using shared resources with incorrect synchronization. Exploiting this vulnerability can allow an attacker to cause a service failure...

AZL-96420 CVE-2026-74375 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: md/raid1,raid10: fix deadlock in read error recovery path raid1d and raid10d may resubmit a split md cloned bio while handling a read error. In this case, resubmitting the bio can lead to a deadlock if the array is suspended befo...

CVE-2026-74372

In the Linux kernel, the following vulnerability has been resolved: raid1: fix nrpending leak in REQATOMIC bad-block error path In raid1writerequest, each per-mirror loop iteration begins by incrementing rdev-nrpending. If a REQATOMIC write encounters a badblock within the requested range, the co...
