In the Linux kernel, the following vulnerability has been resolved: scsi: sd: Fix error handling in sd_probe() after large pool creation failure… (CVE-2026-90268)
A high-severity vulnerability in the Linux kernel's SCSI subsystem (sd driver) related to improper error handling in sd_probe() after a failure in large pool creation has been resolved. The issue involves failure to unregister a disk device after a specific failure, leading to potential resource leaks and inconsistent device state.
AI Analysis
Technical Summary
The vulnerability in the Linux kernel's SCSI sd driver occurs when sd_probe() encounters a failure in sd_large_pool_create() after device_add(&sdkp->disk_dev) has succeeded. The error handling was incorrect because it failed to unregister the disk device and relied on out_free_index kfree() to free resources, which results in freeing an already registered device and leaking the sysfs entry. This flaw could lead to resource leaks and potentially impact system stability or security.
Potential Impact
The vulnerability has a CVSS score of 8.1 (high severity) with impacts on confidentiality, integrity, and availability. Improper error handling and resource leaks in the kernel can lead to system instability or denial of service. No known exploits in the wild have been reported.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel. Users should apply the official kernel updates that address this issue. Since no patch links or vendor advisories are provided in the input, users should monitor official Linux kernel release notes and security advisories for the relevant patch. Patch status is not yet confirmed in the provided data — check the vendor advisory for current remediation guidance.
