CVE-2025-38614 is an insufficient recursion-depth enforcement vulnerability in the Linux kernel eventpoll (epoll) subsystem. The ep_loop_check_proc() function checks for cycles but does not adequately constrain the resulting graph depth: it ignores upward paths and can omit longer downward paths through previously visited subtrees. Additional checks in reverse_path_check() do not fully prevent excessive nesting. Testing on Linux v6.15 demonstrated recursion to approximately 500 levels; whether deeper recursion is possible and how subsequent changes affect the behavior remain uncertain. Excessive recursion can potentially cause kernel stack exhaustion, instability, or denial of service.

A vulnerability affecting Google's sys-kernel/csql-kernel-6_6 package. The advisory provides no technical description, but its CVSS v3 score of 6.2 indicates a local attack requiring no privileges or user interaction, with high availability impact and no confidentiality or integrity impact. Updating to version 18867.199.65 or later addresses the vulnerability.
A vulnerability affecting Google COS kernel packages sys-kernel/csql-kernel-6_12 and sys-kernel/csql-kernel-6_6. The advisory rates it medium severity, with a CVSS v3 base score of 6.2 indicating local exploitation, no required privileges or user interaction, and high availability impact without confidentiality or integrity impact. The underlying technical flaw is not described. The recommended fix is to update sys-kernel/csql-kernel-6_12 and related packages to version 19216.0.47 or later.
