Detailsinfo

A vulnerability was found in Linux Kernel up to 6.10.6. It has been classified as problematic. Affected is the function dasd_ese_needs_format of the component ESE Handler. CWE is classifying the issue as CWE-787. The product writes data past the end, or before the beginning, of the intended buffer. The impact remains unknown. CVE summarizes:

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.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2024-45026 since 08/21/2024. Technical details are known, but there is no available exploit.
