4.7
Média
| Vetor | AV:L/AC:M/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 3.12
Description
The issue is related to a buffer overflow in the exitcode proc write function, which can be exploited by local users with write privileges to the /proc/exitcode file. This could potentially allow users to cause a denial of service or have other unspecified impacts, possibly including privilege escalation. The estimated number of potentially affected devices is not specified.
Recommendations
For Linux kernel versions prior to 3.12, update to version 3.12 or later to resolve the issue. As a temporary workaround, consider restricting write access to the /proc/exitcode file to minimize the risk of exploitation.
