Google: sys-kernel/csql-kernel-6_12, sys-kernel/csql-kernel-6_6: security update to 19216.104.72

high Tenable Cloud Security Plugin ID 467587

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: 9p/trans_fd: p9_fd_request: kick rx
thread if EPOLLIN p9_read_work() doesn't set Rworksched and doesn't do schedule_work(m->rq) if
list_empty(&m->req_list). However, if the pipe is full, we need to read more data and this used to work
prior to commit aaec5a95d59615 ("pipe_read: don't wake up the writer if the pipe is still full").
p9_read_work() does p9_fd_read() -> ... -> anon_pipe_read() which (before the commit above) triggered the
unnecessary wakeup. This wakeup calls p9_pollwake() which kicks p9_poll_workfn() -> p9_poll_mux(),
p9_poll_mux() will notice EPOLLIN and schedule_work(&m->rq). This no longer happens after the optimization
above, change p9_fd_request() to use p9_poll_mux() instead of only checking for EPOLLOUT. (CVE-2025-40305)

Solution

Update the sys-kernel/csql-kernel-6_12 library and its related packages to version 19216.104.72 or later.
