Description OSIDB Bzimport 2026-05-06 10:02:37 UTC 
In the Linux kernel, the following vulnerability has been resolved:

soc: qcom: pd-mapper: Fix element length in servreg_loc_pfr_req_ei

It looks element length declared in servreg_loc_pfr_req_ei for reason
not matching servreg_loc_pfr_req's reason field due which we could
observe decoding error on PD crash.

  qmi_decode_string_elem: String len 81 >= Max Len 65

Fix this by matching with servreg_loc_pfr_req's reason field.
