  2. Vulnerabilities (CVE)
  3. CVE-2024-40971
In the Linux kernel, the following vulnerability has been resolved: f2fs: remove clear SB_INLINECRYPT flag in default_options In f2fs_remount, SB_INLINECRYPT flag will be clear and re-set. If create new file or open file during this gap, these files will not use inlinecrypt. Worse case, it may lead to data corruption if wrappedkey_v0 is enable. Thread A: Thread B: -f2fs_remount -f2fs_file_open or f2fs_new_inode -default_options <- clear SB_INLINECRYPT flag -fscrypt_select_encryption_impl -parse_options <- set SB_INLINECRYPT again

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: f2fs: eliminar el indicador SB_INLINECRYPT en default_options En f2fs_remount, el indicador SB_INLINECRYPT se borrará y se restablecerá. Si crea un archivo nuevo o abre un archivo durante este intervalo, estos archivos no utilizarán inlinecrypt. En el peor de los casos, puede provocar daños en los datos si Wrappedkey_v0 está habilitado. Hilo A: Hilo B: -f2fs_remount -f2fs_file_open o f2fs_new_inode -default_options &lt;- borrar el indicador SB_INLINECRYPT -fscrypt_select_encryption_impl -parse_options &lt;- configurar SB_INLINECRYPT nuevamente
