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.

Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/ath/wcn36xx/main.c 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: https://git.kernel.org/stable/c/ae68efdff7a7a42ab251cac79d8713de6f0dbaa0 https://git.kernel.org/stable/c/e95f9c408ff8311f75eeabc8acf34a66670d8815 https://git.kernel.org/stable/c/64c4dcaeac1dc1030e47883b04a617ca9a4f164e https://git.kernel.org/stable/c/34cd2817708aec51ef1a6c007e0d6d5342a025d7 https://git.kernel.org/stable/c/6200d947f050efdba4090dfefd8a01981363d954
