Doc Text:
A flaw was found in the Linux kernel's SCSI Universal Flash Storage (UFS) core. When the `ufshcd_alloc_host()` function fails to initialize the `hba->rpmbs` list, it can lead to a null pointer dereference during device teardown. This vulnerability could allow a local attacker to cause a system crash, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-08-28 07:46:49 UTC
In the Linux kernel, the following vulnerability has been resolved:

scsi: ufs: core: Initialize hba->rpmbs list in ufshcd

Initialize the hba->rpmbs list in ufshcd_alloc_host() to prevent NULL
pointer dereference in the device teardown path if ufs_rpmb_probe()
fails.
