CVE-2023-53589 Details
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: don't trust firmware n_channels If the firmware sends us a corrupted MCC response with n_channels much larger than the command response can be, we might copy far too much (uninitialized) memory and even crash if the n_channels is large enough to make it run out of the one page allocated for the FW response. Fix that by checking the lengths. Doing a < comparison would be sufficient, but the firmware should be doing it correctly, so check more strictly.
A vulnerability in the Linux kernel's iwlwifi driver can lead to memory corruption and potential crashes. This issue arises when the firmware sends a malformed MCC response with an exaggerated channel count. The driver may then copy excessive amounts of uninitialized memory, risking a crash if the data exceeds the allocated response buffer. The vulnerability has been addressed by implementing stricter length checks on the firmware response.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for upgrading the kernel can be found in the official Linux kernel documentation.
