CVE-2026-99206
scsi: target: iscsi: Fix race in discovery auth updates
Description
In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Fix race in discovery auth updates Separate configfs opens can concurrently update the discovery AuthMethod parameter. Both callers may free the same value in iscsi_update_param_value(), causing a double-free. Protect the lookup and replacement with the discovery TPG access lock, as used by the other TPG configfs parameter updates.
