Buffer Overflows

linux-kvm is vulnerable to buffer overflows. An out-of-bounds OOB memory access flaw was found in x25bind in net/x25/afx25.c in the Linux kernel. A bounds check failure allows a local attacker with a user account on the system to gain access to out-of-bounds memory leading to a system crash or a...

CVE-2016-4580

CVE-2016-4580 affects the Linux kernel up to version 4.5.4 (pre-4.5.5). The vulnerability arises in x25_negotiate_facilities() inside net/x25/x25_facilities.c where a data structure is not properly initialized, enabling an attacker to read sensitive data from kernel stack memory via an X.25 Call ...

Information disclosure

The x25recvmsg function in net/x25/afx25.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a 1 recvfrom, 2 recvmmsg, or 3 recvm...
