Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Wifi: rtw88 – Check whether a PCI upstream bridge exists. The pciupstreambridge function returns NULL if the device is on a root bus. If 8821CE is installed in the system with such a PCI topology, the probing routine will crash...

kernel: wifi: brcmfmac: validate bsscfg indices in IF events

A flaw was found in the Linux kernel's brcmfmac Wi-Fi driver. This vulnerability occurs because the driver fails to properly validate bsscfg indices in interface IF events. An attacker could exploit this by sending a specially crafted IF event with an invalid bsscfg index, which could lead to an...
