| Vetor | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.3.10
Description
A memory leak in the
unittest data add() function in drivers/of/unittest.c allows attackers to cause a denial of service (memory consumption) by triggering of fdt unflatten tree() failures. The relevance of this issue is disputed by third parties because unittest.c can only be reached during boot.Recommendations
For Linux kernel versions prior to 5.3.10, update to version 5.3.10 or later to resolve the issue. As a temporary workaround, consider restricting access to the
unittest data add() function until a patch is available.Correção
