Multiple security vulnerabilities were discovered in the Linux kernel versions used in linux-aws-5.4 and linux-hwe-5.4. These include flaws in the algif_aead cryptographic module and socket buffer handling, which could allow a local attacker to escalate privileges or escape container environments. The vulnerabilities affect several subsystems including Cryptographic API, Packet sockets, RDS protocol, and TLS protocol. Fixes are available in updated kernel versions and should be applied promptly.
