Name of the Vulnerable Software and Affected Versions
grub2 (affected versions not specified)
Description
A flaw was found in grub2 where the
grub extcmd dispatcher() function calls grub arg list alloc() to allocate memory for the grub's argument list. However, it fails to check in case the memory allocation fails. Once the allocation fails, a NULL pointer will be processed by the parse option() function, leading grub to crash or, in some rare scenarios, corrupt the IVT data.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
