Description OSIDB Bzimport 2026-02-14 17:01:14 UTC 
In the Linux kernel, the following vulnerability has been resolved:

platform/x86: toshiba_haps: Fix memory leaks in add/remove routines

toshiba_haps_add() leaks the haps object allocated by it if it returns
an error after allocating that object successfully.

toshiba_haps_remove() does not free the object pointed to by
toshiba_haps before clearing that pointer, so it becomes unreachable
allocated memory.

Address these memory leaks by using devm_kzalloc() for allocating
the memory in question.
