Description

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.

Affected products

• Linux kernel: 3.17 — fixed in 6.19

How to fix

Upgrade to a fixed version: Linux kernel 6.19. Check the vendor advisory for mitigations.
