CVE-2017-7541

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.12.3

Description The issue is related to a buffer overflow in the brcmf cfg80211 mgmt tx function. This can be exploited to cause a denial of service, resulting in a system crash, or potentially to gain privileges. The exploitation involves a crafted NL80211 CMD FRAME Netlink packet.

Recommendations For Linux kernel versions prior to 4.12.3, update to version 4.12.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the brcmf cfg80211 mgmt tx function in the cfg80211.c module to minimize the risk of exploitation.
