linux-intel-iotg can crash or be hijacked
published 4 years ago
Summary
The Linux kernel used in the Intel IoT gateway can be tricked by locally‑run code into crashing the system or running unwanted code. Several parts of the kernel – notification handling, processor instruction handling, asynchronous I/O, networking, and virtual‑machine memory management – have bugs that let an attacker cause a crash or potentially take control. Apply the latest security patches from your Linux distribution and keep the system updated to protect against these risks.
What to do
- Update canonical linux-intel-iotg to version 5.15.0-1017.22.

Original advisory text
linux-intel-iotg vulnerabilities
Selim Enes Karaduman discovered that a race condition existed in the
General notification queue implementation of the Linux kernel, leading to a
use-after-free vulnerability. A local attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-1882)
Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan
and Ariel Sabba discovered that some Intel processors with Enhanced
Indirect Branch Restricted Speculation (eIBRS) did not properly handle RET
instructions after a VM exits. A local attacker could potentially use this
to expose sensitive information. (CVE-2022-26373)
Eric Biggers discovered that a use-after-free vulnerability existed in the
io_uring subsystem in the Linux kernel. A local attacker could possibly use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2022-3176)
It was discovered that the Netlink Transformation (XFRM) subsystem in the
Linux kernel contained a reference counting error. A local attacker could
use this to cause a denial of service (system crash). (CVE-2022-36879)
Jann Horn discovered that the KVM subsystem in the Linux kernel did not
properly handle TLB flush operations in some situations. A local attacker
in a guest VM could use this to cause a denial of service (guest crash) or
possibly execute arbitrary code in the guest kernel. (CVE-2022-39189)
