| Vector | AV:A/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the
authencesn component. The authencesn component assumes an ESP/ESN-formatted AAD (Associated Authentication Data). If the assoclen is less than the minimum expected length, the crypto authenc esn decrypt() function may move beyond the end of the destination scatterlist, resulting in a NULL pointer dereference within the scatterwalk map and copy() function. This can lead to a kernel panic, causing a denial-of-service (DoS) condition. A check for the minimum AAD length has been added to prevent this issue.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
