Vulnerability Details CVE-2022-49815
In the Linux kernel, the following vulnerability has been resolved:
erofs: fix missing xas_retry() in fscache mode
The xarray iteration only holds the RCU read lock and thus may encounter
XA_RETRY_ENTRY if there's process modifying the xarray concurrently.
This will cause oops when referring to the invalid entry.
Fix this by adding the missing xas_retry(), which will make the
iteration wind back to the root node if XA_RETRY_ENTRY is encountered.
