CVE-2026-64522

A flaw was found in the Linux kernel's mlx5e network driver. When handling temporary Security Associations SAs for IPsec, the mlx5exfrmaddstate function incorrectly decrements a counter without a corresponding increment. This underflow in the eswitch mode block mechanism can lead to a denial of...

Linux Distros Unpatched Vulnerability : CVE-2008-1198

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The default IPSec ifup script in Red Hat Enterprise Linux 3 through 5 configures racoon to use aggressive IKE mode instead of main IKE mode, which makes it easi...

Denial Of Service (DoS)

Linux kernal-rt is vulnerable to denial of service. A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker can use this flaw to crash, or potentially...

unauthorized deletion of IPsec SAs in isakmpd, still

1 Abstract For nearly 10 months a handful of OpenBSD-developers is trying to fix a plethora of payload handling flaws in isakmpd. On 2004/01/13 they released something like a final patch to a broader public. The patch protects against some specific attacks, but does not solve the problem. 2...

Re: multiple payload handling flaws in isakmpd, again

There is one important thing I forgot to mention. In isakmpd deleting an IPsec SA also means deleting the appropriate IPsec policy in almost any case. Take a look at pfkeyv2deletespi in pfkeyv2.c. It calls pfkeyv2disablesa, the policy eraser ;-, if the SA was not acquired through the kernel: if...

CVE-2002-0414

KAME-derived implementations of IPsec on NetBSD 1.5.2, FreeBSD 4.5, and other operating systems, does not properly consult the Security Policy Database SPD, which could cause a Security Gateway SG that does not use Encapsulating Security Payload ESP to forward forged IPv4 packets...
