CVE-2026-43067: In the Linux kernel, the following vulnerability has been resolved: ext4: handle wraparound when searching for blocks f

A vulnerability in the Linux ext4 file system could allow certain blocks to be allocated beyond the 32-bit limit for indirect block-mapped files (a way of storing file data using intermediate blocks). This happens when the file system has both extent-mapped files (a more modern storage method) and indirect-block-mapped files, causing a wraparound (overflow) error when searching for available blocks.
