CVE-2026-43475

Name of the Vulnerable Software and Affected Versions Linux kernel version 6.19.0-rc7

Description An issue exists in the scsi storvsc component that causes a scheduling while atomic error and system lock-up when running on Hyper-V with PREEMPT RT enabled. This occurs within the storvsc queuecommand() function.

Recommendations Update the Linux kernel to a version where the fix for the storvsc queuecommand() function has been applied. As a temporary workaround, consider restricting the use of the storvsc module or disabling PREEMPT RT if the system is running on Hyper-V.
