Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nilfs2: handle inconsistent state in nilfs_btnode_create_block()<br /> <br /> Syzbot reported that a buffer state inconsistency was detected in<br /> nilfs_btnode_create_block(), triggering a kernel bug.<br /> <br /> It is not appropriate to treat this inconsistency as a bug; it can occur<br /> if the argument block address (the buffer index of the newly created<br /> block) is a virtual block number and has been reallocated due to<br /> corruption of the bitmap used to manage its allocation state.<br /> <br /> So, modify nilfs_btnode_create_block() and its callers to treat it as a<br /> possible filesystem error, rather than triggering a kernel bug.
