CVE-2024-26956

CVE-2024-26956 covers a kernel vulnerability in nilfs2 within the Linux kernel. The issue has two flaws: (1) nilfs_get_block() may misinterpret a DAT-corrupted data block as existing, due to DAT translation returning -ENOENT; and (2) after this inconsistency, the caller may request a read on an u...
