Title
Kernel: use-after-free after removing device in wb_inode_writeback_end in mm/page-writeback.c
Summary
A use-after-free flaw was found in the Linux Kernel. When a disk is removed, bdi_unregister is called to stop further write-back and waits for associated delayed work to complete. However, wb_inode_writeback_end() may schedule bandwidth estimation work after this has completed, which can result in the timer attempting to access the recently freed bdi_writeback.
Severity ?
7.8 (High)
CWE
