CVE-2026-53319
Description
A flaw was found in the Linux kernel's block writeback throttling (blk-wbt) component. The wbt_init_enable_default() function used a warning mechanism (WARN_ON_ONCE) for expected failure paths during memory allocation or if writeback throttling was already registered. This could lead to spurious warnings, but the failure to initialize writeback throttling is harmless and does not impact the disk's operation.
