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