Description

In the Linux kernel the following vulnerability has been resolved:

gfs2: Truncate address space when flipping GFS2_DIF_JDATA flag

Truncate an inode’s address space when flipping the GFS2_DIF_JDATA flag: depending on that flag the pages in the address space will either use buffer heads or iomap_folio_state structs and we cannot mix the two.
