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.
[ as: commit message and log edits ]
A flaw was found in the Linux kernel's nvdimm/btt module. During the initialization of the Block Translation Table (BTT) via btt_init(), memory allocated for arenas is not properly released if an error occurs. This oversight can lead to a memory leak, potentially impacting system stability or performance over time.
