CVE-2025-39743
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: jfs: truncate good inode pages when hard link is 0 The fileset value of the inode copy from the disk by the reproducer is AGGR_RESERVED_I. When executing evict, its hard link number is 0, so its inode pages are not truncated. This causes the bugon to be triggered when executing clear_inode() because nrpages is greater than 0.

Al ejecutar evict, su número de enlace duro es 0, por lo que sus páginas de inodo no son truncadas. Esto provoca que el bugon se active al ejecutar clear_inode() porque nrpages es mayor que 0."
