Description

In the Linux kernel, the following vulnerability has been resolved: ext4: avoid resizing to a partial cluster size This patch avoids an attempt to resize the filesystem to an unaligned cluster boundary. An online resize to a size that is not integral to cluster size results in the last iteration attempting to grow the fs by a negative amount, which trips a BUG_ON and leaves the fs with a corrupted in-memory superblock.

Affected configurations

• linux linux kernel (< 4.9.326) • linux linux kernel (>= 4.10 < 4.14.291) • linux linux kernel (>= 4.15 < 4.19.256) • linux linux kernel (>= 4.20 < 5.4.211) • linux linux kernel (>= 5.5 < 5.10.138) • linux linux kernel (>= 5.11 < 5.15.63) • linux linux kernel (>= 5.16 < 5.19.4)
