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-2026-74372

A flaw was found in the Linux kernel's RAID1 subsystem. When a REQATOMIC write operation encounters a bad block, a reference to the RAID device rdev is not properly released. This resource leak prevents the affected RAID device from being removed, potentially leading to a denial of service DoS...

CVE-2026-74375

A flaw was found in the Linux kernel's RAID1 and RAID10 subsystems. When handling read errors, a specific sequence of operations involving cloned I/O requests and array suspension can lead to a deadlock. This can cause the system to become unresponsive, resulting in a Denial of Service DoS...

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...

Linux Distros Unpatched Vulnerability : CVE-2026-74372

CVE-2026-74374

In the Linux kernel, the following vulnerability has been resolved: md/raid1,raid10: fix error-path detection with mdclonedbio Detect the error path using mdclonedbio instead of relying on r1bio in raid1 or r10bio-readslot in raid10, which may be NULL or -1 after splitting and resubmitting a fail...

CVE-2026-74373

In the Linux kernel, the following vulnerability has been resolved: md/raid1,raid10: fix bio accounting for split md cloned bios Use mdclonedbio to control bio accounting instead of relying on r1bioexisted in raid1 or the ioaccounting flag in raid10. The previous logic does not reliably reflect...

CVE-2026-74375
