In the Linux kernel, the following vulnerability has been resolved: ocfs2: reject FITRIM ranges shorter than a cluster ocfs2_trim_mainbm() trims the… (CVE-2026-74349)CVE-2026-74349 0 A vulnerability in the Linux kernel's ocfs2 filesystem code was resolved by improving validation of FITRIM ranges. The function ocfs2_trim_mainbm() trims the global bitmap in cluster units but previously only validated range length against the block size, not the cluster size. This allowed FITRIM requests shorter than a cluster but at least one block to be accepted, causing arithmetic underflow and trimming beyond the requested range. The fix rejects FITRIM ranges shorter than the cluster size, preventing zero-cluster trims and preserving expected error behavior.
