Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: perf/core: Fix WARN_ON(!ctx) in
 __free_event() for partial init Move the get_ctx(child_ctx) call and the child_event->ctx assignment to
 occur immediately after the child event is allocated. Ensure that child_event->ctx is non-NULL before any
 subsequent error path within inherit_event calls free_event(), satisfying the assumptions of the cleanup
 code. Details: There's no clear Fixes tag, because this bug is a side-effect of multiple interacting
 commits over time (up to 15 years old), not a single regression. The code initially incremented refcount
 then assigned context immediately after the child_event was created. Later, an early validity check for
 child_event was added before the refcount/assignment. Even later, a WARN_ON_ONCE() cleanup check was
 added, assuming event->ctx is valid if the pmu_ctx is valid. The problem is that the WARN_ON_ONCE() could
 trigger after the initial check passed but before child_event->ctx was assigned, violating its
 precondition. The solution is to assign child_event->ctx right after its initial validation. This ensures
 the context exists for any subsequent checks or cleanup routines, resolving the WARN_ON_ONCE(). To resolve
 it, defer the refcount update and child_event->ctx assignment directly after child_event->pmu_ctx is set
 but before checking if the parent event is orphaned. The cleanup routine depends on event->pmu_ctx being
 non-NULL before it verifies event->ctx is non-NULL. This also maintains the author's original intent of
 passing in child_ctx to find_get_pmu_context before its refcount/assignment. [ mingo: Expanded the
 changelog from another email by Gabriel Shahrouzi. ] (CVE-2025-37878)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.263.49 or later.
