Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-990221 advisory.

 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.
