Kernel Live Patch Security Notice LSN-0053-1
Posted Jul 29, 2019
Authored by Benjamin M. Romer

Vasiliy Kulikov discovered that the Bluetooth stack did not correctly check that device name strings were NULL terminated. A local attacker could exploit this to crash the system, leading to a denial of service, or leak contents of kernel stack memory, leading to a loss of privacy. It was discovered that the Linux kernel on ARM processors allowed a tracing process to modify a syscall after a seccomp decision had been made on that syscall. A local attacker could possibly use this to bypass seccomp restrictions. Various other issues were also addressed.

A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition leading to a use-after-free existed in the Reliable Datagram Sockets protocol implementation in the Linux kernel. The RDS protocol is blacklisted by default in Ubuntu. If enabled, a local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
