mpi3mr driver

About this tag
The mpi3mr driver is a Linux kernel SCSI driver for Broadcom/LSI MPI3 storage controllers, commonly used in enterprise servers and Azure Linux environments. Discussions on WindowsForum.com focus on security vulnerabilities (CVE-2023-53376, CVE-2024-57804, CVE-2025-37861) that have been fixed upstream. These include a bitmap size calculation bug causing out-of-bounds memory access, a race/logic bug during firmware operations, and a race condition between task-management and reset threads. Microsoft's Azure Linux attestations confirm the driver is included and potentially affected by these CVEs, but the statements are scoped to Azure Linux only. The tag covers kernel security patches, memory handling fixes, and race condition resolutions for the mpi3mr driver.

    CVE-2023-53376 Linux mpi3mr Fix: Bitmap Size Corrected to Bits

    A subtle but dangerous memory-handling bug in the Linux kernel’s mpi3mr SCSI driver — tracked as CVE-2023-53376 — has been fixed upstream after maintainers discovered that the driver was calculating bitmap sizes in bytes while calling bitmap helper functions that expect sizes in bits, allowing...

    Azure Linux Attestation for CVE-2024-57804: What It Means for Azure and Beyond

    Microsoft’s public attestation that “Azure Linux includes this open‑source library and is therefore potentially affected” should be read as a deliberate, product‑scoped inventory statement — authoritative for Azure Linux, useful for automation, but not proof that no other Microsoft product can...

    CVE-2025-37861: Linux mpi3mr Driver Fix and Azure Linux Attestation

    The Linux kernel defect tracked as CVE-2025-37861 — a race in the SCSI mpi3mr driver where the task‑management (tm) thread can access an invalid reply‑queue ID while a reset thread is in progress — has been fixed upstream, and Microsoft’s public advisory confirms that Azure Linux images include...
