CVE-2026-43473

CVSS3: 5.5

Описание

In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Add NULL checks when resetting request and reply queues The driver encountered a crash during resource cleanup when the reply and request queues were NULL due to freed memory. This issue occurred when the creation of reply or request queues failed, and the driver freed the memory first, but attempted to mem set the content of the freed memory, leading to a system crash. Add NULL pointer checks for reply and request queues before accessing the reply/request memory during cleanup

A flaw was found in the Linux kernel's mpi3mr SCSI driver. When the creation of reply or request queues fails, the driver may attempt to access and modify memory that has already been freed during cleanup. This can be exploited by a local user, leading to a system crash and a Denial of Service (DoS).

Отчет

Red Hat acknowledges the upstream Linux kernel correction for «scsi» as described in COMMENT_ZERO. Fixes are delivered through standard kernel errata for supported products. Operational exposure depends on whether this subsystem or driver is active in your configuration.
