https://notcve.org/view.php?id=CVE-2022-48668
In the Linux kernel, the following vulnerability has been resolved: smb3: fix temporary data corruption in collapse range collapse range doesn't discard the affected cached region so can risk temporarily corrupting the file data. This fixes xfstest generic/031 I also decided to merge a minor cleanup to this into the same patch (avoiding rereading inode size repeatedly unnecessarily) to make it clearer. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: smb3: corrige la corrupción temporal de datos en el rango de contracción el rango de contracción no descarta la región en caché afectada, por lo que puede correr el riesgo de corromper temporalmente los datos del archivo. Esto corrige xfstest generic/031. También decidí fusionar una limpieza menor en el mismo parche (evitando volver a leer el tamaño del inodo repetidamente innecesariamente) para que quede más claro. • https://git.kernel.org/stable/c/5476b5dd82c8bb9d0dd426f96575ae656cede140 https://git.kernel.org/stable/c/49523a4732204bdacbf3941a016503ddb4ddb3b9 https://git.kernel.org/stable/c/fa30a81f255a56cccd89552cd6ce7ea6e8d8acc4 •

In the Linux kernel, the following vulnerability has been resolved: scsi: core: Fix a use-after-free There are two .exit_cmd_priv implementations. Both implementations use resources associated with the SCSI host. Make sure that these resources are still available when .exit_cmd_priv is called by waiting inside scsi_remove_host() until the tag set has been freed.
