Description

nilfs2: handle inconsistent state in nilfs_btnode_create_block()

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: handle inconsistent state in nilfs_btnode_create_block()

Syzbot reported that a buffer state inconsistency was detected in

nilfs_btnode_create_block(), triggering a kernel bug.

It is not appropriate to treat this inconsistency as a bug; it can occur

if the argument block address (the buffer index of the newly created

block) is a virtual block number and has been reallocated due to

corruption of the bitmap used to manage its allocation state.

So, modify nilfs_btnode_create_block() and its callers to treat it as a

possible filesystem error, rather than triggering a kernel bug.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
