4.4

Média

VetorAV:L/AC:M/Au:N/C:P/I:P/A:P
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 2.6.39
Description The issue is related to the cifs close function in the Linux kernel, which can cause a denial of service due to a NULL pointer dereference and BUG when the O DIRECT flag is set during an attempt to open a file on a CIFS filesystem. This could potentially have other unspecified impacts.
Recommendations For Linux kernel versions prior to 2.6.39, update to version 2.6.39 or later to resolve the issue. As a temporary workaround, consider avoiding the use of the O DIRECT flag when opening files on a CIFS filesystem until the kernel is updated.
