CVE-2022-40982
Daniel Moghimi discovered Gather Data Sampling (GDS), a hardware
vulnerability for Intel CPUs which allows unprivileged speculative
access to data which was previously stored in vector registers.
This mitigation requires updated CPU microcode provided in the
intel-microcode package.

CVE-2023-20569
Daniel Trujillo, Johannes Wikner and Kaveh Razavi discovered
INCEPTION, also known as Speculative Return Stack Overflow (SRSO),
a transient execution attack that leaks arbitrary data on all AMD
Zen CPUs. An attacker can mis-train the CPU BTB to predict non-
architectural CALL instructions in kernel space and use this to
control the speculative target of a subsequent kernel RET,
potentially leading to information disclosure via a speculative
side-channel.

For Debian 9 stretch, these problems have been fixed in version 5.10.179-5~deb9u1.
