What to do
AI-suggested
The vulnerability has been resolved in the Linux kernel by correcting the source of the scsi_pointer during selection. Users should apply the official Linux kernel updates that include this fix once available. Patch status is not explicitly confirmed in the provided data, so users should monitor vendor advisories for the fixed kernel versions and apply updates accordingly.
Description
CVE-2024-50026 is a medium severity vulnerability in the Linux kernel's wd33c93 SCSI driver. It is caused by a regression where a stale scsi_pointer value is used during device selection, leading to a kernel oops (crash). The issue stems from improper initialization of the scsi_pointer variable from hostdata->connected before it is valid. The fix involves correctly obtaining the scsi_pointer from hostdata->selecting during selection.
