  "description": "In 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.",
