028ee64de34e983ec3d8254cdcf7763efc9ce93bd02e9c211623229d73e4533cUbuntu Security Notice 4660-2 - USN-4660-1 fixed vulnerabilities in the Linux kernel. Unfortunately, that update introduced a regression in the software raid10 driver when used with fstrim that could lead to data corruption. This update fixes the problem. It was discovered that a race condition existed in the perf subsystem of the Linux kernel, leading to a use-after-free vulnerability. An attacker with access to the perf subsystem could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

Unfortunately, that update introduced a regression in the software raid10 driver when used with fstrim that could lead to data corruption. This update fixes the problem. It was discovered that a race condition existed in the binder IPC implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

An attacker with access to the perf subsystem could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the frame buffer implementation in the Linux kernel did not properly handle some edge cases in software scrollback. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

A local attacker could use this to cause a denial of service or possibly execute arbitrary code. 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.
