DescriptionJason Donenfeld discovered a heap overflow in the MACsec module in the Linux kernel. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected packages.
