CVE-2026-72223

Published Aug 15, 2026 EPSS 0.22% (12th pctl)

Overview

CVE-2026-72223 is a known-severity vulnerability. It was published on August 15, 2026.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

nvdimm/btt: Free arena sub-allocations on discover_arenas() error path

Memory allocated by btt_freelist_init(), btt_rtt_init(), and

btt_maplocks_init() is not freed on some discover_arenas() error

paths. This leaks memory when arena discovery fails.

Add the missing kfree() calls to release the allocations before

returning an error.
