Description OSIDB Bzimport 2025-10-01 12:08:55 UTC 
In the Linux kernel, the following vulnerability has been resolved:

s390/dasd: Fix potential memleak in dasd_eckd_init()

`dasd_reserve_req` is allocated before `dasd_vol_info_req`, and it
also needs to be freed before the error returns, just like the other
cases in this function.
