NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

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

nvdimm/btt: Free arenas on btt_init() error paths

The arenas allocated by discover_arenas() or create_arenas() are not freed on some error paths in btt_init(). This leaks memory when BTT initialization fails.

Call free_arenas() from the affected error paths to release the allocations.
