CVE-2026-53284 is a vulnerability in the Linux kernel's Btrfs filesystem where dirty pages in the IO tree are released even after failed writes. This improper cleanup can lead to warnings and errors during filesystem unmount, including forced readonly states and aborted transactions. The issue arises because the dirty pages IO tree is cleared prematurely when write errors occur, preventing proper cleanup of dirty extent buffers.
