CVE-2026-90385 md/raid1: create serial pool adding rdev to array with serialize_policy=1

In the Linux kernel, the following vulnerability has been resolved: md/raid1: create serial pool adding rdev to array with serializepolicy=1 The following bug has been observed with kernel 7.1.3 after adding a new rdev to an existing RAID1 array with serializepolicy enabled: Oops: 0002 1 CPU: 0...

CVE-2026-90275

CVE-2026-90275 is a Linux kernel bug in the md/raid1 (Software RAID mirror) driver. In raid1_takeover(), the code sets conf->array_frozen = 1 on the newly-allocated r1conf structure, but nothing subsequently clears it. This became impactful after commit b39f35ebe86d ("md: don't quiesce in mdde...

In the Linux kernel, the following vulnerability has been resolved: md/raid1: don't set arrayfrozen in raid1takeover raid1takeover sets conf-arrayfrozen = 1 on the newly-allocated r1conf and nothing ever clears it, so every I/O to the array stalls permanently once waitbarrier sees it stuck at 1...

The vulnerability in the md/raid1.c component of the Linux operating system’s kernel allows a hacker to cause a service failure.

The vulnerability in the md/raid1.c component of the Linux kernel lies in the fact that resources are not released after their useful lifespan has ended. 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...
