Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

i2c: Fix a potential use after free

Free the adap structure only after we are done using it. This patch just moves the put_device() down a bit to avoid the use after free.

[wsa: added comment to the code, added Fixes tag]

Affected: Ubuntu:Pro:14.04:LTS: linux-aws, Ubuntu:Pro:14.04:LTS: linux-lts-xenial, Ubuntu:Pro:16.04:LTS: linux, Ubuntu:Pro:16.04:LTS: linux-aws, Ubuntu:Pro:16.04:LTS: linux-kvm

It was discovered that a race condition existed in the instruction emulator of the Linux kernel on Arm 64-bit systems. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-20422)

Wei Chen discovered that a race condition existed in the TIPC protocol implementation in the Linux kernel, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1382)

Jose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2 mitigations with prctl syscall were insufficient in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2023-1998)

Daniele Antonioli discovered that the Secure Simple Pairing and Secure Connections pairing in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials. A physically proximate attacker placed between two Bluetooth devices could use this to subsequently impersonate one of the paired devices. (CVE-2023-24023)

shanzhulig discovered that the DRM subsystem in the Linux kernel contained a race condition when performing certain operation while handling driver unload, 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-2023-51043)
