kernel: ext4: avoid deadlock in fs reclaim with page writeback
In the Linux kernel, the following vulnerability has been resolved: ext4: avoid deadlock in fs reclaim with page writeback Ext4 has a filesystem wide lock protecting ext4writepages calls to avoid races with switching of journalled data flag or inode format. This lock can however cause a deadlock...
kernel: use-after-free after removing device in wb_inode_writeback_end in mm/page-writeback.c
A use-after-free flaw was found in the Linux Kernel. When a disk is removed, bdiunregister is called to stop further write-back and waits for associated delayed work to complete. However, wbinodewritebackend may schedule bandwidth estimation work after this has completed, which can result in the...
