Medium
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel version 3.10.x
Description
The issue is related to a flaw in the Linux kernel that allows userspace to call functions like
memcpy fromiovecend() with a zero offset and buffer length, causing a read beyond buffer boundaries. This can lead to a memory access fault and a system halt by accessing an invalid memory address. The exploitation of this issue may allow an attacker to cause a denial of service.Recommendations
For Linux kernel version 3.10.x, consider disabling the
memcpy fromiovecend() function as a temporary workaround until a patch is available. Restrict access to similar functions that may cause buffer boundary overflows to minimize the risk of exploitation.Exploit
Fix
Out of bounds Read
