In the Linux kernel, the following vulnerability has been resolved:
s390/dasd: fix error recovery leading to data corruption on ESE devices
Extent Space Efficient (ESE) or thin provisioned volumes need to be
formatted on demand during usual IO processing.
The dasd_ese_needs_format function checks for error codes that signal
the non existence of a proper track format.
The check for incorrect length is to imprecise since other error cases
leading to transport of insufficient data also have this flag set.
This might lead to data corruption in certain error cases for example
during a storage server warmstart.
Fix by removing the check for incorrect length and replacing by
explicitly checking for invalid track format in transport mode.
Also remove the check for file protected since this is not a valid
ESE handling case.
A flaw was found in the kernel. The s390/dasd component, responsible for handling Extent Space Efficient (ESE) devices, contains an error in its recovery process. An imprecise check for data length during on-demand formatting of ESE volumes can lead to incorrect error handling. This vulnerability can result in data corruption, especially during events such as a storage server warmstart.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
