CVE-2025-37826:
Linux Debian vulnerability analysis and mitigation
Overview
In the Linux kernel, a vulnerability has been identified and assigned CVE-2025-37826. The issue involves a missing NULL pointer check in the ufshcdmcqcomplpendingtransfer() function within the SCSI UFS core component. This vulnerability was discovered and disclosed on May 8, 2025 (NVD).
Technical details
The vulnerability stems from the absence of a NULL pointer validation for the hwq pointer returned by ufshcdmcqreqtohwq() function. This implementation is similar to a previous vulnerability that was fixed in commit 74736103fb41 ("scsi: ufs: core: Fix ufshcdabortone racing issue"). The issue resides in the SCSI UFS core component of the Linux kernel (NVD).
Impact
A NULL pointer dereference in the kernel can lead to system crashes or denial of service conditions, potentially affecting system stability and availability (Tenable).
Mitigation and workarounds
The vulnerability has been resolved by adding a NULL check for the returned hwq pointer by ufshcdmcqreqtohwq(). This fix has been implemented in the Linux kernel codebase (NVD).
