Bottlerocket: bottlerocket-kernel-5.15, kernel-5.15: security update to 5.15.178

high Tenable Self-Hosted Container Security Plugin ID 428166

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: gpiolib: cdev: Fix use after free in
lineinfo_changed_notify The use-after-free issue occurs as follows: when the GPIO chip device file is
being closed by invoking gpio_chrdev_release(), watched_lines is freed by bitmap_free(), but the
unregistration of lineinfo_changed_nb notifier chain failed due to waiting write rwsem. Additionally, one
of the GPIO chip's lines is also in the release process and holds the notifier chain's read rwsem.
Consequently, a race condition leads to the use-after-free of watched_lines. Here is the typical stack
when issue happened: [free] gpio_chrdev_release() --> bitmap_free(cdev->watched_lines) <-- freed -->
blocking_notifier_chain_unregister() --> down_write(&nh->rwsem) <-- waiting rwsem -->
__down_write_common() --> rwsem_down_write_slowpath() --> schedule_preempt_disabled() --> schedule() [use]
st54spi_gpio_dev_release() --> gpio_free() --> gpiod_free() --> gpiod_free_commit() -->
gpiod_line_state_notify() --> blocking_notifier_call_chain() --> down_read(&nh->rwsem); <-- held rwsem -->
notifier_call_chain() --> lineinfo_changed_notify() --> test_bit(xxxx, cdev->watched_lines) <-- use after
free The side effect of the use-after-free issue is that a GPIO line event is being generated for
userspace where it shouldn't. However, since the chrdev is being closed, userspace won't have the chance
to read that event anyway. To fix the issue, call the bitmap_free() function after the unregistration of
lineinfo_changed_nb notifier chain. (CVE-2024-36899)
