Title
platform/x86: toshiba_haps: Fix memory leaks in add/remove routines
Summary
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.
Severity
No CVSS data available.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
