Subject: CVE-2024-57997: wifi: wcn36xx: fix channel survey memory allocation size
Date: Wed, 26 Feb 2025 18:05:56 -0800 [thread overview]
Message-ID: <2025022640-CVE-2024-57997-a004@gregkh> (raw)
Description
===========
In the Linux kernel, the following vulnerability has been resolved:
wifi: wcn36xx: fix channel survey memory allocation size
KASAN reported a memory allocation issue in wcn->chan_survey
due to incorrect size calculation.
This commit uses kcalloc to allocate memory for wcn->chan_survey,
ensuring proper initialization and preventing the use of uninitialized
values when there are no frames on the channel.
The Linux kernel CVE team has assigned CVE-2024-57997 to this issue.

Mitigation
==========
The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes. Individual
changes are never tested alone, but rather are part of a larger kernel
release. Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all. If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
