service.


* CVE-2023-52458: Denial-of-service in the block layer.

Incorrect error checking in the kernel's block layer support when

to cause a denial-of-service.


* CVE-2024-26852: Privilege escalation when using IPV6 multipath routes.

A logic error when using IPV6 multipath routes could lead to a
