Red Hat Security Advisory 2021-4140-02 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include buffer overflow, bypass, denial of service, double free, heap overflow, information leakage, null pointer, out of bounds read, and use-after-free vulnerabilities.

4dfc7aebdc7ac022001a4c7d69c2bd52229c03ec9dfec7f38b9b87cefa159f78Ubuntu Security Notice 4910-1 - Ryota Shiga discovered that the sockopt BPF hooks in the Linux kernel could allow a user space program to probe for valid kernel addresses. A local attacker could use this to ease exploitation of another kernel vulnerability. It was discovered that the BPF verifier in the Linux kernel did not properly handle signed add32 and sub integer overflows. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
