Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> erofs: fix missing xas_retry() in fscache mode<br /> <br /> The xarray iteration only holds the RCU read lock and thus may encounter<br /> XA_RETRY_ENTRY if there&amp;#39;s process modifying the xarray concurrently.<br /> This will cause oops when referring to the invalid entry.<br /> <br /> Fix this by adding the missing xas_retry(), which will make the<br /> iteration wind back to the root node if XA_RETRY_ENTRY is encountered.
