  "details": "In the Linux kernel, the following vulnerability has been resolved:  ext4: fix buffer_head leak in ext4_init_orphan_info  ext4_init_orphan_info() reads orphan file blocks with ext4_bread() and stores the returned buffer_head in oi-\u003eof_binfo[i].ob_bh.  If ext4_bread() succeeds but the orphan block magic or checksum validation fails, the function jumps to out_free. However, the old out_free loop starts releasing buffers from i - 1, so the current buffer_head at index i is skipped.  This leaks the buffer_head reference obtained by ext4_bread() on the bad magic and bad checksum error paths.  Fix this by tracking the number of successfully read buffer_heads and releasing exactly those buffer_heads on the error path.",
