Answer in brief
CVE-2024-0646 records a High severity (CVSS 7.0) vulnerability in Kernel: ktls overwrites readonly memory pages when using function splice with a ktls socket as destination. The current sources do not mark it as known exploited. Affected software not mapped in the current feed; confirm the named product and version against your inventory.

An out-of-bounds memory write flaw was found in the Linux kernel’s Transport Layer Security functionality in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user to crash or potentially escalate their privileges on the system.
