In the Linux kernel, the following vulnerability has been resolved: Wifi: iwlwifi: dbg-tlv: Ensure NUL termination The iwlfwiunidebuginfotlv is used as a string; therefore, we must ensure that the string is terminated correctly before using it...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iwlwifi: fix use-after-free If no firmware was present at all or, presumably, all of the firmware files failed to parse, we end up unbinding the driver by calling devicereleasedriver, which calls remove. This then calls iwldrvsto...
