Analyze and fix the following issue in the Linux kernel code: nvme: null terminate nvme_tls_attrs
Problem Details: Commit 1e48b34c9bc7 ("nvme: split off TLS sysfs attributes into a separate group") introduced the struct attribute array nvme_tls_attrs. However, the array was not null terminated and caused BUG KASAN global- out-of-bounds. To avoid the BUG, null terminate the array. Reported-by: Yi Zhang <yi.zhang@re...
