| Vetor | AV:L/AC:M/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions through 3.12.1
Description
The issue is related to the
aac send raw srb function in the Linux kernel, which does not properly validate a certain size value. This can be exploited by local users with CAP SYS ADMIN privileges to cause a denial of service or possibly have other unspecified impacts via a crafted SRB command using the FSACTL SEND RAW SRB ioctl call. Local users can potentially elevate their privileges by exploiting the aacraid driver.Recommendations
For Linux kernel versions through 3.12.1, consider restricting access to the
FSACTL SEND RAW SRB ioctl call to minimize the risk of exploitation. As a temporary workaround, consider disabling the aac send raw srb function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
