CVE-2026-53015

A flaw was found in the Linux kernel's erofs filesystem. On 32-bit platforms, the lcn variable, used for logical cluster numbers, was defined as a 32-bit integer. This could lead to truncation when calculating offsets larger than 4 Gigabytes GiB, potentially causing incorrect data handling within...
