Accessing the pointer in this case will cuase an out-of-bound access. Fix this by checking n_ssids first. The Linux kernel CVE team has assigned CVE-2024-40929 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/intel/iwlwifi/mvm/scan.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/3c4771091ea8016c8601399078916f722dd8833b https://git.kernel.org/stable/c/f777792952d03bbaf8329fdfa99393a5a33e2640 https://git.kernel.org/stable/c/9e719ae3abad60e245ce248ba3f08148f375a614 https://git.kernel.org/stable/c/29a18d56bd64b95bd10bda4afda512558471382a https://git.kernel.org/stable/c/62e007bdeb91c6879a4652c3426aef1cd9d2937b https://git.kernel.org/stable/c/60d62757df30b74bf397a2847a6db7385c6ee281
