CVE-2026-74369: Linux

EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: liveupdate: fix u-a-f in luo_file_unpreserve_files() and luo_file_finish() In luo_file_unpreserve_files() and luo_file_finish(), reorder module_put() and xa_erase() to ensure the file handler module remains pinned while its operations are being accessed. Specifically, luo_get_id() dereferences fh->ops->get_id, so the module reference must be held until after xa_erase() (which calls luo_get_id) completes. For luo_file_finish(), this requires moving the module_put() call out of the luo_file_finish_one() helper and into the main loop of luo_file_finish() itself.

Affected products

• Linux Linux: from 7.1, before 7.1.5 (fixed in 7.1.5)
