What the advisory describes

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. [ as: commit message and log edits ]

Source: EUVD (ENISA), in the words of the advisory.

Does this concern one of your customers?

This page cannot answer that — it does not know your estate. Whoever has recorded their environments gets the answer the morning after publication, together with a paragraph they can forward to the customer unedited.

Patchlage reports hits and suspected hits. About everything else this system says nothing — neither this page nor the situation report ever claims that an estate is safe.
