- CWE-416
Description
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.
Affected configurations
• linux linux kernel (>= 5.15 < 5.15.164)
• linux linux kernel (>= 5.16 < 5.19.6)
• linux linux kernel 6.0
• redhat enterprise linux 8.0
• redhat enterprise linux 9.0
