CVE-2026-31431 NOMISEC HIGH WORKING POC
crypto: algif_aead - Revert to operating out-of-place
In the Linux kernel, the following vulnerability has been resolved: crypto: algif_aead - Revert to operating out-of-place This mostly reverts commit 72548b093ee3 except for the copying of the associated data. There is no benefit in operating in-place in algif_aead since the source and destination come from different mappings. Get rid of all the complexity added for in-place operation and just copy the AD directly.
CVSS 7.8
CVE-2022-27666 WRITEUP HIGH WRITEUP
Linux Kernel < 5.17 - Heap Buffer Overflow in IPsec ESP Transformation
A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat.
CVSS 7.8
CVE-2013-2237 WRITEUP WRITEUP
Linux Kernel < 3.9 - Information Disclosure via IPSec Key Socket Notify Policy
The key_notify_policy_flush function in net/key/af_key.c in the Linux kernel before 3.9 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel heap memory by reading a broadcast message from the notify_policy interface of an IPSec key_socket.
