Kernel Live Patch Security Notice LSN-0074-1
Posted Feb 1, 2021
Authored by Benjamin M. Romer

Elena Petrova discovered that the pin controller device tree implementation in the Linux kernel did not properly handle string references. A local attacker could use this to expose sensitive information (kernel memory). Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux kernel did not properly initialize memory in some situations. A physically proximate remote attacker could use this to expose sensitive information (kernel memory). Various other issues were also addressed.

Ubuntu Security Notice USN-4657-1
Posted Dec 2, 2020

Ubuntu Security Notice 4657-1 - Elena Petrova discovered that the pin controller device tree implementation in the Linux kernel did not properly handle string references. A local attacker could use this to expose sensitive information. Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered that legacy pairing and secure-connections pairing authentication in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. A physically proximate attacker could use this to impersonate a previously paired Bluetooth device. Various other issues were also addressed.
