CVE-2026-64360 Detail
Received
This CVE record has recently been published to the CVE List and has been included within the NVD dataset. DescriptionIn the Linux kernel, the following vulnerability has been resolved: hfs/hfsplus: zero-initialize buffer in hfs_bnode_read hfs_bnode_read() can return early without writing to the output buffer when is_bnode_offset_valid() fails or when check_and_correct_requested_ length() corrects the length to zero. Callers such as hfs_bnode_read_ u16() and hfs_bnode_read_u8() pass stack-allocated buffers and use the result unconditionally, leading to KMSAN uninit-value reports. Rather than initializing at each individual call site, zero the buffer at the start of hfs_bnode_read() before any validation checks. This ensures all callers in both hfs and hfsplus get a deterministic zero value regardless of which early-return path is taken. Metrics
