Multiple security vulnerabilities were discovered in the Linux kernel low latency hardware enablement (HWE) 5.15 series, including a flaw in the algif_aead cryptographic module known as Copy Fail. These issues affect subsystems such as the Cryptographic API, Ethernet bonding driver, Packet sockets, and TLS protocol. A local attacker could exploit these vulnerabilities to escalate privileges or potentially escape container environments. The vulnerabilities are addressed in the linux-lowlatency-hwe-5.15 kernel update version 5.15.0-179.189~20.04.1.
