CVE-2024-45026

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> s390/dasd: fix error recovery leading to data corruption on ESE devices<br /> <br /> Extent Space Efficient (ESE) or thin provisioned volumes need to be<br /> formatted on demand during usual IO processing.<br /> <br /> The dasd_ese_needs_format function checks for error codes that signal<br /> the non existence of a proper track format.<br /> <br /> The check for incorrect length is to imprecise since other error cases<br /> leading to transport of insufficient data also have this flag set.<br /> This might lead to data corruption in certain error cases for example<br /> during a storage server warmstart.<br /> <br /> Fix by removing the check for incorrect length and replacing by<br /> explicitly checking for invalid track format in transport mode.<br /> <br /> Also remove the check for file protected since this is not a valid<br /> ESE handling case.
