Google: sys-kernel/csql-kernel-6_1, sys-kernel/lakitu-kernel-6_1: security update to 18244.151.9

high Tenable Cloud Security Plugin ID 451784

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: cachefiles: flush all requests after
setting CACHEFILES_DEAD In ondemand mode, when the daemon is processing an open request, if the kernel
flags the cache as CACHEFILES_DEAD, the cachefiles_daemon_write() will always return -EIO, so the daemon
can't pass the copen to the kernel. Then the kernel process that is waiting for the copen triggers a
hung_task. Since the DEAD state is irreversible, it can only be exited by closing /dev/cachefiles.
Therefore, after calling cachefiles_io_error() to mark the cache as CACHEFILES_DEAD, if in ondemand mode,
flush all requests to avoid the above hungtask. We may still be able to read some of the cached data
before closing the fd of /dev/cachefiles. Note that this relies on the patch that adds reference counting
to the req, otherwise it may UAF. (CVE-2024-40935)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.151.9 or later.
