Description OSIDB Bzimport 2026-06-24 18:07:34 UTC 
In the Linux kernel, the following vulnerability has been resolved:

block: fix zones_cond memory leak on zone revalidation error paths

When blk_revalidate_disk_zones() fails after disk_revalidate_zone_resources()
has allocated args.zones_cond, the memory is leaked because no error path
frees it.
