Description OSIDB Bzimport 2026-08-15 06:09:37 UTC 
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.
